This performs a consistent renaming of the issuance authorizing key to make it consistent with the ZIP.
It also reworks the `IssuanceAuthorizingKey` struct in place of the `IssuanceKey` and `IssuanceAuthorizingKey` structs, as part of using a two key structure for issuance, as specified in ZIP 227.
Added burn validation, fixes and minor additions.
Bumped Rust version to 1.65

Updated constants for master (extended) issuance key according to ZIP
227. Previously, we used the same personalization for the master
extended spending key and the master extended issuance key, as well as
the same purpose constant for the spending master key and the issuance
master key.
Now, the following updates have been made:
- Personalization for the master extended issuance key: ZIP32ZSAIssue_V1
- Purpose constant for the issuance master key: 227"
1. Added a new error, `ValueSumOverflow`, that occurs if the sum value overflows when adding new supply amounts.
2. Created a new `supply_info` module containing `SupplyInfo` and `AssetSupply` structures, with `add_supply` function and unit tests for it.
3. Renamed the `are_note_asset_ids_derived_correctly` function to `verify_supply`, changed its behavior to verify and compute asset supply, added unit tests for it.
4. Updated the `verify_issue_bundle` function to use the changes mentioned above, updated its description, and added new unit tests.
5. Renamed errors with `...NoteType` suffix in the name to `...AssetBase`.
6. Added `update_finalization_set` method to `SupplyInfo` and use after the calls of `verify_issue_bundle function` (if needed), instead of mutating the finalization set inside `verify_issue_bundle`.
