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.

[dni]

bump :)

[prusnak]

Please merge and make a new release on PyPI, this is making the library unusable with modern python versions.

If you are not able to merge in time (it's been 8 months since the coincurve 21.x release), maybe just let's just drop the upper bound, so we do not hit the same issue again next time coincurve is updated.

[darosior]

Fair enough, i'll get to it and i think i'll also drop the upper bound.

that would be awesome!

coincurve are bumping their major version aggressively even though there are no API breaking changes so this makes sense.

[darosior]

I cherry-picked your second commit in a PR dedicated to properly move the project away from our deprecated ways: #49. I plan to make a first release for the project structure change, followed by merging the Coincurve version bump and a second release.

[darosior]

I have a separate PR which supersedes this one to upgrade to Coincurve. Unfortunately it seems to fail CI because of ofek/coincurve#187 at the moment. I'll get a release PR together to be ready to publish a new release as soon as it's resolved.
