Changelog

Added input checking to a range of functions to guard against segfaults with empty input (#31)

Added support for OKLab and OKLch (polar version of OKLab) colour spaces
Added encode_native() and decode_native() to convert back and forth between the internal R colour format.

Fixed a bug in colour comparison where the blue channel got ignored (#20, @krlmlr)
Allowing "NA" and "transparent" as valid colour names
How NA should be treated can now be set in all functions accepting colour names

Small adjustments to support super weird architectures (#15, #16)
decode_colour() now allows you to specify how NA should get interpreted
Fixed a major bug in colour comparison
Colour names are now stripped of whitespace and converted to lower-case before conversion, making it behave like col2rgb()
An error is now emitted if an unknown colour name is passed into any decoding function

Added a NEWS.md file to track changes to the package.
Remove Rcpp dependency for faster compilation. (#6)
Add support for Lch(uv) (Hcl) for parallel to grDevices::hcl() (#9)
