feat!: Move all feature extractors into namespace only + speedup Lempel Ziv

[abstractqqq]

Improved performance for Lempel Ziv by applying the change to Hashbrown suggested by Ritchie

BREAKING CHANGE:

1. The functime.feature_extraction.tsfresh module is merged into functime.feature_extractor. This has 2 advantages: (a). Simpler, keeping things in one place and shorter import path. (b) This avoids a potential circular import. If we write plugin code, the code needs to be registered in a namespace (in feature_extractor.py), but for Series to benefit from it, we have to import the code to tsfresh.py. But feature_extractor module imports from tsfresh.py... Hence the circular import. Merging them together solves this issue
