* clarify the dependency on ZIP 316 Revision 1;
* move the main point of the specification of Alternative 2 to be higher up;
* clarify the semantics of UAs with both shielded Receivers and Source
Restriction Metadata with value Transparent Source Only, and recommend
against producing them.

This change ensures that wallets that have not yet been updated to ZIP
316 Revision 1 will fail to recognise Unified Addresses with
MUST-understand metadata, and consequently will not violate any
restrictions imposed on transfers by those metadata items'
requirements.

This makes it clear that the encoding of `ik` used in the Asset Base
derivation is big-endian, as in the case of the underlying BIP 340
Schnorr signature scheme.
It also adds a clarification about the version byte used in the Asset
Base derivation.
We switch the `issueAuthSig` scheme from RedPallas without
key re-randomization to the Bitcoin Schnorr signature (as described in
bip340).
We also perform notation changes of `idk` to `imk`, and adjust the
derivation of the issuance keys to fit with the updated Issuance
Authorization Signature scheme.
This removes the transaction structure fields from ZIP 226 in favour
of adding them to ZIP 230, for the v6 Transaction Format.

This rearranges the positioning of the burn mechanism in order to remove duplication of material between the burn mechanism section and the value balance verification section.
There is also some simplification of the naming convention for the Asset Base variable.
This PR improves the naming of variables to make them consistent with
the broader ZIPs conventions.
It also makes changes to the issuance key derivation and the terms used
for the various keys.
This PR adds missing indices over sums. It also fixes and makes improvements to the burn mechanism description.

Removed redundant terminology in ZIP226, building on ZIP227, fixed abstract and used consistent terminology to stick to issuance instead of creation of assets.

This makes the naming conventions for variables more consistent, largely with a view to using double backticks for terms that appear in the transaction format and datatype description tables.
These tables have also been reformatted to be consistent with other ZIPs in their rst form.
The `previously_finalized` set is renamed to `finalized_assets`, and this set now stores `AssetDigest` values rather than `AssetId` values for more compactness in the global state.
This adds details of the changes to the Orchard Action encodings and
the changes to the transaction format that occur due to the ZSA
Protocol. It also improves the formatting of existing tables for Asset
Burn.
