numfmt: align format output values with GNU (#1745) 
When converting to SI or IEC, produce values that align with the conventions
used by GNU numfmt.

- values > 10 are represented without a decimal place, so 10000 becomes 10K
  instead of 10.0K

- when truncating, take the ceiling of the value, so 100001 becomes 101K

- values < 10 are truncated to the highest tenth, so 1001 becomes 1.1K

numfmt: handle leading whitespace & implied padding (#1721) 
Align with GNU numfmt by trimming leading whitespace from supplied values.
If the user did not specify a padding, calculate an implied padding from
the leading whitespace and the value.

Also track closer to GNU numfmt’s error message format.

26aa1f346e ls: only print colors if stdout is a tty 
Previously if no --color argument was input, we would always print
colors in the output. This breaks `configure` scripts which run `ls`
and then compare the output against what they expect to see, since the
left side has ANSI escape sequences and the right side doesn't.

Instead, only print escape sequences if a TTY is present, or if
`--color=always` is specified.

Fixes #1638.

ls: On Windows don't display files hidden by NTFS (#1662) 
This little check, allows us to hide the files that
shouldn't be shown on the listing on Windows operating
systems.

Just like the "dot" in UNIX based operating systems
Windows uses its own file attributes to determine if a file
is hidden or not.

The lack of support for this option is normally an annoyance
for many users, this commit adds full support for this feature

Gabriel Ganne
607b70a896 base32/base64: tolerate non-utf8 encoded inputs 
For inputs that are valid base64 but that encode non-utf8 strings (like
garbage), base64 panicks when trying to unwrap the result from
String::from_utf8().
Instead of interpreting the byte stream as utf8, simply dump the raw
bytes to stdout.

Since the test assert that all io is valid utf8, this does not come with
a unit test. See run() in tests/common/utils.rs.

6539b8c6b9 maint/deps ~ change version specification for dependencies between sub-packages 
- refactor internal version specifications to be ">=M.m.p" (where M.m.p is *already published*)

## [why]

Loosening internal version dependencies decreases the coupling between packages such
that packages can be published in a looser order. It allows the packages to be version
updated and published in tandem (ie, by using `cargo workspace ...`). Once published,
the internal versions can then be updated (again, to an *already published* package
version), as needed.

b7b0c76b8e factor::Decomposition: Optimise as a factor is never added twice 
The invariant is checked by a debug_assert!, and follows from the previous
commit, as `dec` and `factors` only ever contains coprime numbers:
  - true at the start: factor = ∅ and dec = { n¹ } ;
  - on every loop iteration, we pull out an element `f` from `dec` and either:
    - discover it is prime, and add it to `factors` ;
    - split it into a number of coprime factors, that get reinserted into `dec`;
      the invariant is maintained, as all divisors of `f` are coprime with all
      numbers in `dec` and `factors` (as `f` itself is coprime with them.

As we only add elements to `Decomposition` objects that are coprime with the
existing ones, they are distinct.

sort: fix panic on write to closed pipe 
If the output of sort is piped to another program that closes the file
descriptor, sort currently panics. The GNU coreutils is able to handle
this case.

Replacing panic with crash_if_err reports the closed pipe and exits
with a return code, which seems like the correct behavior. Tested on
my Mac and the panic disappears.

Add a test which pipes data to sort - it won't protect against this
specific regression, but it increases the test coverage, at least.

Fixes #1608.

3e55139c13 factor::miller_rabbin::Result: Mark as #[must_use] 
Ignoring a value of that type is a bug: they are only produced by
`miller_rabbin::test`, which is a pure, but expensive, function.

As such, an ignored value is always either a mistake, or an easy
optimisation opportunity (just remove the useless call to `test`).

8e040bbf1a factor::table: Optimise the size of the precomputed table 
A too-large precomputed table actually slows down the program: we spend
time fetching it from disk and from memory (into the CPU's cache), and
larger prime factors are more unlikely to occur in random integers (prime p
occurs with probability ~1/p when sampling 64b numbers uniformly-at-random)

The new value was chosen after measuring the execution time (for all
integers between 2 and 10⁷) for a broad set of values:
