This function implements CBOR canonicalisation (RFC 7049):

• Map keys are sorted lexicographically
• Indefinite-length mapslists are converted to finite-length mapslists
• The representation of the CBOR major types is as small as possible (provided by "cborg" package)

This function implements only CBOR canonicalisation from CIP-21. Other requirements from CIP-21 are not implemented.

2. CIP-21: https://github.com/cardano-foundation/CIPs/blob/master/CIP-0021/README.md#canonical-cbor-serialization-format

This function implements CBOR canonicalisation at the Term level:

• Map keys are sorted lexicographically
• Indefinite-length mapslists are converted to finite-length mapslists
