Switch from cryptonite to crypton

[erikd]

The former is deprecated in favor of the latter which is is drop in replacement. This change also requires a bump in the major version of cardano-crypto-class and related packages from 2.1.* to 2.2.*. No changes are required in Plutus for this change, but cardano-ledger does not currently support 2.2.*.

This PR should not be merged until the two SRPs added in this PR are removed.

This can be merged because this master already contains stuff that breaks cardano-ledger (seems that initUPLCSimplifierTrace has been dropped or moved).
