zstd==1.5.2.5 for wheels on PyPI

[altendky]

Presently we have to get zstd wheels from our own https://pypi.chia.net/simple/ instead of official PyPI. It would be nice to get away from needing our own repo for the three main platforms.

Draft for:

• [ ] diff review
  • [x] https://github.com/sergey-dryabzhinsky/python-zstd/compare/v1.5.0.4..v1.5.2.5
  • [ ] https://github.com/facebook/zstd/compare/a488ba114ec17ea1054b9057c26a046fc122b3b6...e47e674cd09583ff0503f0f6defd6d23d8b718d3

My apologies to all who got pinged when I pasted the changelog. I should have done it as a code block. :[
