feat(config): allow colours in both rgb and hex

This commit introduces the ability for users to specify colours in the
static config file in either RGB or Hex format.

This is done by introducing a new enum, Colour, which provides variants
wrapping the internal Rgb type, and the HexColour type from the
hex_colour crate. HexColour itself is wrapped in a new struct, Hex, in
order to allow the implementation of the JsonSchema trait.

A number of From<T> implementations have been done in order to make
working with the Colour enum more ergonomic.

Ultimately, the core representation for colours in komorebi remains the
Rgb struct, any and Hex-specified colours will be converted to this Rgb
type before being converted to u32 to pass them on to various Win32 API
calls.
