Update to make some minor grammar changes and add ABNF grammar definition and rules from RFC 9110 which defines user-agent strings in the web context

Update to include a best-guess estimate of ledger growth based on implementing this with some references. Also updated references and added relevant footnote markers in the text.

Minor update to highlight all RFC 2119 keywords in the text

* Proposal of canonical ledger state format

This proposal defines the Simple Canonical Ledger State (SCLS),
a stable, versioned, and verifiable file format for representing
the Cardano ledger state. It specifies a segmented binary container
with deterministic CBOR encodings, per-chunk commitments, and
a manifest that enables identical snapshots across implementations,
supports external tools (e.g., Mithril), and future-proofs distribution
and verification of state.

* CIP: CLS — upadte META Record structure

Use cbor data in metadata value.
It will allow other software store structured introspectable metadata
in file.

* Update file structure.

Rewrite file structure definition and format.cddl

* Update CIP-015x/README.md

* Canonical Ledger State, set CIP number

* Update CIP-0165/format.cddl

Co-authored-by: Alexey Kuleshevich <[email protected]>

* Update CIP-0165/namespaces/README.md

Co-authored-by: Alexey Kuleshevich <[email protected]>

* Move to more explicit terms, slot_no instead of transaction

* CIP-0165: be more explicit about data validation

* Add an explicit declaratio that this CIP does not define how ledger stores state

* Add information about the manifest record

Add offset so it would be possible to reconcstruct manifest by reading the file
from the end.

Add number of entries and chunks per-namespace

Add a comment about the spec

* Clarify tombstone and value deletion (#2)

* Clarify tombstone and value deletion

During an implementation it because obvous that it's easier to keep tombstones
an explicit value in delta blocks. In this MR we remove obsolete tombstone/v0
namespaces and update spec

* Explicitly require keys for entries

* Add clarification about tombstone entries

* CIP-0165: specification of the binary file (#5)

* CIP-0165: specification of the binary file

Provide a binary file specification in Kaitai Struct format
as well as html description of the format and svg diagram

* Fix format

* Update keys (#6)

* Explicitly describe the length of the record payload

* Drop len_data field, we already know it because we can calculat that from datastructure size

* Introduce structure for the entries and a fixed size keys

This commit introduces a fixed size keys the size of the key depends on the
namespace that is used.

This approach allows us not to waste time on the encoding of the size
for each key and allows to have nice and fast keys for each namespace
used.

* remove tombstone namespace from the list of the namespaces

* Update CIP to explicitly tell how we deal with trees

* Update CIP-0165/README.md

* Removed slot_no from the delta record

* Add explicit key size definition for namespace in format.ksy

* Revert human readable names to tags

* Update representation utxo

* Remove pots/v0 namespace as it's can be derived from the other parts of the state

* Change footer entries_count type from u64 to u32

Updated footer entry count type from u64 to u32 for consistency.

* Remove network_id enum from format.ksy

Removed network_id enum definitions from format.ksy.

* Clarify namespace ordering and Merkle tree ambiguities

- CHUNK records are ordered by namespace, bytewise/UTF-8
- Merkle nodes use the `0x00` domain separator
- Merkle trees are unbalanced, with a "promote depth" behaviour on
  trailing nodes
- Global Merkle root is computed from the per-namespace Merkle roots
- Empty Merkle tree is H("")
