Encompassing decoder for substrate/polkadot/kusama types.
Gets type definitions from polkadot-js via JSON and decodes them into components that outline types and make decoding byte-strings possible, as long as the module/generic type name are known.
Supports Metadata versions from v8, which means all of Kusama (from CC1). Older networks are not supported (E.G Alexander).
- makes decoding generic types from the substrate rpc possible
- requires parsing JSON with type definitions, and implementing traits
TypeDetectiveandDecoderin order to work for arbitrary chains. However, if the JSON follows the same format as PolkadotJS definitions (look atdefinitions.jsonandoverrides.json) it would be possible to simply deserialize into Polkadot structs and utilize those. The decoding itself is generic enough to allow it. - types must adhere to the conventions set out by polkadot decoding
- type definitions for Polkadot (Kusama) are taken from Polkadot.js and deserialized into Rust (extras/polkadot)

Note: Release description is in no way complete because of current & active development for legacy desub types & scale-info based types. it is purely here as a record for things that should be taken into account in the future
- Depending on changes in legacy desub code, bump version in Cargo.toml for
extras/,core/ - note
upgrade-blockspresent here and modify the hard-coded upgrade blocks as necessary in the desubruntimes.rsfile.- NOTE: this step may-or-may not be necessary depending on
scale-infointegration in the future.
