facaefc49c Add conversions for TweakedKeyPair -> TweakedPublicKey (Tobin C. Harding)
2407f241e4 Remove sep256k1 path from Parity (Tobin C. Harding)
Pull request description:
It is trivially possible to get `TweakedPublicKey` from a `TweakedKeyPair`, add conversion methods for doing so.
Patch 1 is preparatory cleanup. Please note `From` is not implemented because the conversion returns the `Parity` also.
Fix: #1452
