Closes #15 by supporting in-place updates.

introduces new functor API inspired by ImageBinarization.jl in file dither_api.jl
- supports dither! and custom output types
- optional kwarg to_linear which calls Colors.invert_srgb_compand is now abstracted out of dithering algorithms
Introduces new algorithm ClosestColor, which rounds each pixel to closest color in palette
- added example in docs
adds more tests

Currently the tests only fail on color error diffusion algorithms due to small rounding errors compared to the reference tests: https://github.com/JuliaImages/DitherPunk.jl/pull/16/checks?check_run_id=2813126426#step:7:404
