Anirudha Bose bdab8dfe81 chaincfg: Add RegisterHDKeyID func to populate HD key ID pairs
Currently, the only way to register HD version bytes is by initializing
chaincfg.Params struct, and registering it during package init.
RegisterHDKeyID provides a way to populate custom HD version bytes,
without having to create new chaincfg.Params instances. This is useful
for library packages who want to use non-standard version bytes for
serializing extended keys, such as the ones documented in SLIP-0132.

This function is complementary to HDPrivateKeyToPublicKeyID, which is
used to lookup previously registered key IDs.
