* WIP integrating new frame-decode and working out new storage APIS
* WIP: first pass adding new storage things to subxt-core
* Second pass over Address type and start impl in Subxt
* WIP new storage APIs
* WIP New storage APIs roughly completed, lots of errors still
* Remove PlainorMap enum; plain and map values now use same struct to simplify usage
* Begin 'fixing' errors
* WIP splitting errors and tidying payload/address traits
* Get subxt-core compiling
* Small fixes in subxt-core and remove metadata mod
* subxt-core: cargo check --all-targets passes
* Fix test
* WIP starting to update subxt from subxt-core changes
* WIP splitting up subxt errors into smaller variants
* WIP errors: add DispatchError errors
* Port new Storage APIs to subxt-core
* cargo check -p subxt passes
* Quick-fix errors in subxt-cli (explore subcommand)
* fmt
* Finish fixing codegen up and start fixing examples
* get Subxt examples compiling and bytes_at for constants
* Add some arcs to limit lifetimes in subxt/subxt-core storage APIs
* A little Arcing to allow more method chaining in Storage APIs, aligning with Subxt
* Update codegen test
* cargo check --all-targets passing
* cargo check --features 'unstable-light-client' passing
* clippy
* Remove unused dep in subxt
* use published frame-decode
* fix wasm-example

* Fix doc tests and fix bug getting constant info
* Fix V14 -> Metadata transform for storage & constants
* Fix parachain example
* Fix FFI example
* BlockLength decodes t ostruct, not u128
* use fetch/iter shorthands rather than entry in most storage tests
* Fix some integration tests
* Fix Runtime codegen tests
* Expose the dynamic custom_value selecter and use in a UI test
* Update codegen metadata
* Tidy CLI storage query and support (str,str) as a storage address
* Add (str,str) as valid constant address too
* Show string tuple in constants example
* Via the magic of traits, avoid needing any clones of queries/addresses and accept references to them
