Wave-chunk-parser

Allows the reading of CART chunks from Reaper and resolves an issue with label encoding. Behind the scenes we've moved to Poetry from pip.

Pulls in the work of ahihi to align generated blobs with word boundaries, resolving 169 in the process.

Brings in 167, support for user Chunk and RIFF file parsing.

Brings in the work of fdenivac on 165:

- support for PCM 24 bits with datas stored as 3 raw bytes : samples must be converted by user before processing
- support for extended formats. Extension format is stored as bytes. Changes FormatChunk constructor signature
- force chunks and list sub-chunks to be aligned on a word
- tests adapted to new FormatChunk constructor

A slight change to the API thanks to 163 but adds support for new chunk types.

Includes 159 which adds Note and LabeledText sub-chunks to ListChunk.
