Instead of just writing output to a file (or buffer), build the complete result css as a data tree. This is a requirement for implementing @extend, and it cleans up some of the ouptput/transform code. Also some actual improvement in at-rule / rule interaction.

Instead of just writing output to a file (or buffer), build the
complete result css as a data tree.  This is a requirement for
implementing `@extend`, and it cleans up some of the ouptput/transform
code.  Also some actual improvement in at-rule / rule interaction.

Progress: 4604 of 6925 tests passed.

* Changed repo structure to a monorepo (PR #164).
  - The commandline interface now lives in the separate crate rsass-cli.
  - The test updater also have a separate crate, but not intended for
    publication.
  - Tests are restructured to fail faster for simple things, while
    macos and windows testing is added to the github action (appveyor
    is removed).
* Added macros (PR #163, #165).
  - The workspace now includes a `rsass-macros` crate that can be used to
    compile sass to css strings at compile time in rust crates.
* Changed numeric handing (mainly conversions to/from `f64`) to match
  improvements in how dart-sass handles numerics.  This is mainly done by
  removing some special cases as dart-sass and rust now agrees on more of
  those.
* Added new variables `$epsilon`, `$max-safe-integer`, `$min-safe-integer`,
  `$max-number`, and `$min-number` in `sass:math`, matching recent dart-sass
  additions.
* Added new `split()` function in `sass:string` module.
* Changed the span type used in parsing to a local type that borrows a
  `SourceFile` instead of `nom_locate` dependency (PR #158).
* Changed the type `SourceFile` to be reference counted, so cloned
  `SourceFile` objects share the same actual data (PR #158).
* Moved the `SourcePos` type into the `input` module and converted it from
  keeping a copy of the relevant line to keeping a range with a (reference
  counted) `SourceFile` (PR #158).
* Changed css creation from just writing to a text buffer to building
  a tree representation of the css (and serialize it to text as a
  final step) (PR #159).
* Changed `BinOp` value in both sass and css from a tuple variant with
  boxed values to a single boxed struct variant.
* Improved value checking; Report an error if trying to output invalid
  css values in some cases. Also, arithmetic involving colors that
  used to be calculated is now correctly invalid (PR #161).
* Changed `css::Item::AtRule` to wrap the new type `css::AtRule`.
* More varaints of `Invalid`, slightly fewer stringy errors.
* Changed handling of `hue` arguments to color functions, to allow
  different angle units, matching updates in sass-spec.
* Minor correctness improvent in the `calc` function handling.
* Clippy now takes MSRV from Cargo.toml.  Slightly more recent lints allowed.
* Updated clap to 4.0 for the command-line interface.
* Updated sass-spec test suite to 2023-01-06.

Thanks to @Wicpar for the initial macros implementation.
