Upgrade coincurve versioning to allow 21.x

[ofek]

This upgrades coincurve to v21.0.0 which brings performance improvements and removes all runtime dependencies!

Thanks! Unfortunately CI is now failing on Coincurve installation:

I can make CI pass if you want but how long do you plan to support 3.8?

[darosior]

I don't think this is related to 3.8. It also fails on the 3.10 job, and i suspect it would fail on all of them given enough time.

[ofek]

I think I found the issue, can you please run CI once more?

The Python packaging ecosystem has standardized on the interface for build backends (PEP 517/PEP 660) and the format for metadata declaration (PEP 621/PEP 631). As a result, the execution of setup.py files is now deprecated.

[darosior]

Unfortunate that the CI doesn't run automatically anymore, just kicked it let's see.

[ofek]

Yay all green now!

[darosior]

Hi, just letting you know i did not forget about this.
