* Remove panic from BlockCommands run function
Instead of panicing, the run method now returns an error to prevent
nushell from unexpected termination.
* Add ability to open command to run with blocks
The open command tries to parse the content of the file
if there is a command called 'from (file ending)'. This works
fine if the command was 'built in' because the run method doesn't
fail in this case. It did fail on a BlockCommand, though.
This change will first probe if the command contains a block and
evaluate it, if this is the case. If there is no block, it will run
the command the same way as before.

* Add streaming support to save for ExternalStream data
Prior to this change, save would collect data from an ExternalStream (data
originating from externals) consuming memory for the full amount of data piped
to it,
This change adds streaming support for ExternalStream allowing saving of
arbitrarily large files and bounding memory usage.
* Remove broken save test
This test passes but not for the right reasons, since this test was
written filename has become a required parameter. The parser outputs
an error but the test still passes as is checking the original un-mutated
file assuming save has re-written the contents.
This change removes the test.

Currently, doing:

* Fix typo
* Add subcommand `into filesize`
It's currently not possible to convert a number or a string containing a number
into a filesize. The only way to create an instance of filesize type today is
with a literal in nushell syntax. This commit adds the `into filesize`
subcommand so that file sizes can be created from the outputs of programs
producing numbers or strings, like standard unix tools.
There is a limitation with this - it doesn't currently parse values like `10 MB`
or `10 MiB`, it can only look at the number itself. If the desire is there, more
flexible parsing can be added.
* fixup! Add subcommand `into filesize`
* fixup! Add subcommand `into filesize`
* Allow environment variables to be hidden
This change allows environment variables in Nushell to have a value of
`Nothing`, which can be set by the user by passing `$nothing` to
`let-env` and friends.
Environment variables with a value of Nothing behave as if they are not
set at all. This allows a user to shadow the value of an environment
variable in a parent scope, effectively removing it from their current
scope. This was not possible before, because a scope can not affect its
parent scopes.
This is a workaround for issues like #3920.
Additionally, this allows a user to simultaneously set, change and
remove multiple environment variables via `load-env`. Any environment
variables set to $nothing will be hidden and thus act as if they are
removed. This simplifies working with virtual environments, which rely
on setting multiple environment variables, including PATH, to specific
values, and remove/change them on deactivation.
One surprising behavior is that an environment variable set to $nothing
will act as if it is not set when querying it (via $nu.env.X), but it is
still possible to remove it entirely via `unlet-env`. If the same
environment variable is present in the parent scope, the value in the
parent scope will be visible to the user. This might be surprising
behavior to users who are not familiar with the implementation details.
An additional corner case is the the shorthand form of `with-env` does
not work with this feature. Using `X=$nothing` will set $nu.env.X to the
string "$nothing". The long-form works as expected: `with-env [X
$nothing] {...}`.
* Remove unused import
* Allow all primitives to be convert to strings
Given we can write nu scripts. As the codebase grows, splitting into many smaller nu scripts is necessary.
In general, when we work with paths and files we seem to face quite a few difficulties. Here we just tackle one of them and it involves sourcing
files that also source other nu files and so forth. The current working directory becomes important here and being on a different directory
when sourcing scripts will not work. Mostly because we expand the path on the current working directory and parse the files when a source command
call is done.
For the moment, we introduce a `lib_dirs` configuration value and, unfortunately, introduce a new dependency in `nu-parser` (`nu-data`) to get
a handle of the configuration file to retrieve it. This should give clues and ideas as the new parser engine continues (introduce a way to also know paths)
With this PR we can do the following:
Let's assume we want to write a nu library called `my_library`. We will have the code in a directory called `project`: The file structure will looks like this:
```
project/my_library.nu
project/my_library/hello.nu
project/my_library/name.nu
```
This "pattern" works well, that is, when creating a library have a directory named `my_library` and next to it a `my_library.nu` file. Filling them like this:
```
source my_library/hello.nu
source my_library/name.nu
```
```
def hello [] {
"hello world"
}
```
```
def name [] {
"Nu"
end
```
Assuming this `project` directory is stored at `/path/to/lib/project`, we can do:
```
config set lib_dirs ['path/to/lib/project']
```
Given we have this `lib_dirs` configuration value, we can be anywhere while using Nu and do the following:
```
source my_library.nu
echo (hello) (name)
```
