Update pypi with latest blosc version

[mroeschke]

It appears that the latest version on conda-forge is 1.21.1: https://anaconda.org/conda-forge/blosc

It appears that the latest version on pypi is 1.10.6: https://pypi.org/project/blosc/#history

It would be great if pypi could be updated with the latest blosc version; otherwise, is pypi still supported?

I think there is a misunderstanding here. 1.21.1 is the version of the C-Blosc library (in conda-forge they are using the somewhat confusing blosc name for that). And 1.10.6 is the (latest) version of the Python-Blosc package and it does exist in PyPI.

At any rate, there is the relatively new Python-Blosc2 package that exposes a very similar API (just a bit more modernized, like e.g. using Enums for codecs and filters, and other bells and whistles) than Python-Blosc. Also, its conda-forge name, python-blosc2, is way more appropriate.

Ah I didnt know there was a difference between the C and Python library (including naming)

Also not sure if I'm missing something, but I don't see python-blosc2 on conda-forge: https://anaconda.org/search?q=python-blosc2

% mamba install -c conda-forge python-blosc2

Just to clarify my motivation: I am trying to resolve blosc as an optional dependency in pandas and how to install on pip & conda

So for blosc it would be?

Pypi: pip install blosc (latest version 1.10.6)
Conda: conda install -c conda-forge python-blosc (latest version 1.10.6)

And for blosc2 it would be
Pypi: pip install blosc2 (latest version 0.5.2)
Conda: ?
