Describe the bug
R1 signatures are not generated properly.

To Reproduce
Steps to reproduce the behavior:

1. Try to sign data with an R1 key.
2. Try to recover public key from signature.

Expected behavior

1. You may or may not receive an error about high r values. (needs canonical check)
2. You won't receive the correct public key. (needs recovery parameter updates)

Additional context
#731 is where the bug was originally reported. This issue will track progress. New PR will be created to add tests and another update for canonical checking.
