Reverts #1323

I am pretty sure I confirmed #1323 before it was merged. Why revert?

Pretty sure it's spam

All right, closing. Will reopen if given a reason.

Afaict the BIP continues to have incorrect test vectors.

Per the tests in the Bitcoin Core, the base64 signature of "Hello World", with key from bip, should be:

AkgwRQIhAOzyynlqt93lOKJr+wmmxIens//zPzl9tqIOua93wO6MAiBi5n5EyAcPScOjf1lAqIUIQtr3zKNeavYabHyR8eGhowEhAsfxIAMZZEKUPYWI4BruhAQjzFT8FSFSajuFwrDL1Yhy

I get this result in my JS implementation.

In the bip0322-signatures repo (bottom of notebook), @wip-abramson says they'll make a PR to update this. But, it looks like it wa updated with yet another result.
