After the scripted changes, the changes to BIP-40, BIP-41, and BIP-63
were undone, because it breaks CI.
These three BIPs only exist conceptually and their proposal documents
are missing which causes changes to them ot break the CI. I defer the
changes to these BIPs to a separate pull request to get CI to pass.
Author confused bip-0341, which defines the Taproot construction, with bip-0342, which defines the
Tapscript scripting system. Unknown key types are defined in the latter, as part of the semantics of
the CHECKSIG{VERIFY} and CHECKSIGADD opcodes.
