Release 0.28.4

Released 2023-11-11.
.

* Filter out placeholder selectors when writing the resulting css
  (they are still parsed of the internal data representation, so they
  can be used when implementing `@extend`) (PR #180).
* Filter out some other illegal / never-matching selectors (PR #181).
* Some improvements in plain css value parsing:
  - trailing comma and space separated lists in function arguments.
  - unqoted urls (contining slash and dot) in function arguments.
  - Negative numbers and numbers starting with a decimal dot.
  - unicode-ranges.
* Allow at-rules in at-rules when parsing plain css.
* Refactored function name/plain string handling in scss values to not parse
  the same unquoted string twice.
* Remove separate backref member from `css::Selectors` for cleanup before
  implementing more selector functions.  Instead, add it to an internal
  struct `SelectorCtx` (PR #179).
* Implemented a bunch of css math functions.  They differ from the
  functions in the math module in that they fallback to themself if
  the answer cant be calculated but isn't obviously wrong
  (e.g. `min(var(--gap), 2em)` is preserved while `min(1em, 2em)` is
  evaluated to `1em` and `min(1s, 1em)` yields an error).  This also
  includes some improvements in handling numeric zeroes and
  infinities. (PR #184).
* Implemented css relative color functions (PR #185).
* Simplify units early in numeric division and multiplication.  I
  think this is a bit uglier, but it is more consistent with dart
  sass.
* Refactored some parsers for less backtracking, making it easier to point
  parse errors at the right place in the code and maybe making parsing
  slightly more efficient.
* Improve selector / name parsing by beeing more restrictive (PR #183).
* Updated sass-spec test suite to 2023-10-31.
