Previously the layout used the floor of the calculated start and width
as the value to use for the split Rects. This resulted in gaps between
the split rects.
This change modifies the layout to round to the nearest column instead
of taking the floor of the start and width. This results in the start
and end of each rect being rounded the same way and being strictly
adjacent without gaps.
Because there is a required constraint that ensures that the last end is
equal to the area end, there is no longer the need to fixup the last
item width when the fill (as e.g. width = x.99 now rounds to x+1 not x).
The colors example has been updated to use Ratio(1, 8) instead of
Percentage(13), as this now renders without gaps for all possible sizes,
whereas previously it would have left odd gaps between columns.
* feat(table): add option to configure selection layout changes
Before this option was available, selecting a row in the table when no row was selected
previously made the tables layout change (the same applies to unselecting) by adding the width
of the "highlight symbol" in the front of the first column, this option allows to configure this
behavior.
* refactor(table): refactor "get_columns_widths" to return (x, width)
and "render" to make use of that
* refactor(table): refactor "get_columns_widths" to take in a selection_width instead of a boolean
also refactor "render" to make use of this change
* fix(table): rename "highlight_set_selection_space" to "highlight_spacing"
* style(table): apply doc-comment suggestions from code review

* 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
- control over the style of each cell and its content using the styling capabilities of Text.
- rows with multiple lines.
- fix panics on small areas.
- less generic type parameters.
* Fix percentage and ratio constraints for table to take borders into account
Percentage and ratio constraints don't take borders into account, which causes
the table to not be correctly aligned. This is easily seen when using 50/50
percentage split with bordered table. However fixing this causes the last column
of table to not get printed, so there is probably another problem with columns
width determination.
* Fix rounding of cassowary solved widths to eliminate imprecisions
* Fix formatting to fit convention
