EIP4844: Remove reliance on py-ecc types in polynomial-commitments and add py-arkworks

[kevaundray]

Description

Currently the polynomial-commitments file relies on py-ecc types and methods. This can be seen with the usage of bls.Z1 and bls.G1. If we do plan to use another library, removing this decoupling is a necessary pre-requisite.

Changes

• Removed Z2 and FQ from imports in bls.py as they were not being used
• aliased all py_ecc direct imports that we need for 4844 with a py_ecc prefix
• Added wrapper methods which for now directly call py_ecc, but in the future can conditionally call a different library

Note

I have intentionally not tried to change method names, so the changes in polynomial-commitments are easy to grep.

EDIT:

• Dankrad has also added in the py-arkworks library into this PR.

Hey @kevaundray, I just realized my PyPy3.9 was built with 0.3.2 because 0.3.3 doesn't provide "Source Distributions" on PyPi. Could you upload the source distributions for 0.3.3?

Also, for completeness, it would be nice to upload macos Python3.9 distributions too. 🙏

@hwwhww I've added 3.8 to 3.11 along with source distributions in version 0.3.4, please let me know if anything else is missing :)

Closing as this was merged into #3274 which was merged into dev yesterday
