`Paragraph` now supports rendering each line in the paragraph with a
different alignment (Center, Left and Right) rather than the entire
paragraph being aligned the same. Each line either overrides the
paragraph's alignment or inherits it if the line's alignment is
unspecified.
- Adds `alignment` field to `Line` and builder methods on `Line` and
`Span`
- Updates reflow module types to be line oriented rather than symbol
oriented to take account of each lines alignment
- Adds unit tests to `Paragraph` to fully capture the existing and new
behavior

- `Default::default` is hard to read
- a few `map` -> `map_or`
- simplified `match` -> `let-if`

Adds a `border!` macro that takes TOP, BOTTOM, LEFT, RIGHT, and ALL and
returns a Borders object. An empty `border!()` call returns
Borders::NONE
This is gated behind a `macros` feature flag to ensure short build
times. To enable, add the following to your `Cargo.toml`:
```toml
ratatui = { version = 0.21.0, features = ["macros"] }
```

* refactor: add Line type to replace Spans
`Line` is a significantly better name over `Spans` as the plural causes
confusion and the type really is a representation of a line of text made
up of spans.
This is a backwards compatible version of the approach from
https://github.com/tui-rs-revival/ratatui/pull/175
There is a significant amount of code that uses the Spans type and
methods, so instead of just renaming it, we add a new type and replace
parameters that accepts a `Spans` with a parameter that accepts
`Into<Line>`.
Note that the examples have been intentionally left using `Spans` in
this commit to demonstrate the compiler warnings that will be emitted in
existing code.
Implementation notes:
- moves the Spans code to text::spans and publicly reexports on the text
module. This makes the test in that module only relevant to the Spans
type.
- adds a line module with a copy of the code and tests from Spans with a
single addition: `impl<'a> From<Spans<'a>> for Line<'a>`
- adds tests for `Spans` (created and checked before refactoring)
- adds the same tests for `Line`
- updates all widget methods that accept and store Spans to instead
store `Line` and accept `Into<Line>`
* refactor: move text::Masked to text::masked::Masked
Re-exports the Masked type at text::Masked
* refactor: replace Spans with Line in tests/examples/docs
* build: bump MSRV to 1.65

Also fixes several clippy warnings added in 1.63/1.65. Although these
have been since moved to nursery / pedantic, it doesn't hurt to fix
these issues as part of this change:
- https://rust-lang.github.io/rust-clippy/master/index.html#derive_partial_eq_without_eq (nursery)
- https://rust-lang.github.io/rust-clippy/master/index.html#bool_to_int_with_if (pedantic)
Adds a new type Masked that can mask data with a mask character, and can
be used anywhere we expect Cow<'a, str> or Text<'a>. E.g. Paragraph,
ListItem, Table Cells etc.
BREAKING CHANGE:
Because Masked implements From for Text<'a>, code that binds
Into<Text<'a>> without type annotations may no longer compile
(e.g. `Paragraph::new("".as_ref())`)
To fix this, annotate or call to_string() / to_owned() / as_str()
- also adds builder methods on list state to make it easy to construct
a list state with selected and offset as a one-liner. Uses `with_` as
the prefix for these methods as the selected method currently acts as
a getter rather than a builder.
- cargo tarpaulin suggests only two lines are not covered (the two
match patterns of the self.start_corner match 223 and 227).
the body of these lines is covered, so this is probably 100% coverage.
- The implementation of Debug is customized to make it easy to use the
output (particularly the content) directly when writing tests (by
surrounding it with `Buffer::with_lines(vec![])`). The styles part of
the message shows the position of every style change, rather than the
style of each cell, which reduces the verbosity of the detail, while
still showing everything necessary to debug the buffer.
```rust
Buffer {
area: Rect { x: 0, y: 0, width: 12, height: 2 },
content: [
"Hello World!",
"G'day World!",
],
styles: [
x: 0, y: 0, fg: Reset, bg: Reset, modifier: (empty),
x: 0, y: 1, fg: Green, bg: Yellow, modifier: BOLD,
]
}
```
- The assert_buffer_eq! macro shows debug view and diff of the two
buffers, which makes it easy to understand exactly where the difference
is.
- Also adds a unit test for buffer_set_string_multi_width_overwrite
which was missing from the buffer tests
Fixes issue #680. Handles the case where a list item is created with an empty string, which is not split by the lines iterator.
