New primitives for aiken/crypto/bls12_381, completing coverage of the BLS12-381 builtins:

- pairing.mul: to multiply two MillerLoopResult together, aggregating pairings before a final verification.
A new type-alias in cardano/assets: Tokens = Dict<AssetName, Int>
from_data and expect_from_data functions have been added to:
- aiken/collection/list
- aiken/collection/pairs
from_value has been added to aiken/collection/dict
to_value and from_value functions to cardano/assets.
replicate added to aiken/primitive/bytearray

⚠️ BREAKING-CHANGE ⚠️
Value has been renamed to Assets, to leave room to the new builtin-Value.
⚠️ BREAKING-CHANGE ⚠️
cardano/transaction/script_purpose.{compare} now follows the ledger's ordering of script purposes, which is the ordering of the redeemers list in the script context:
- Spend < Mint < Publish < Withdraw < Vote < Propose.
It previously followed the constructor order of ScriptPurpose (Mint first, Withdraw before Publish), which does not match the on-chain ordering. See #125.
