* 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 * Add new tx extension to fix daily tests * Remove unused subxt_core::dynamic::DecodedValue type * Update book to match changes * Update docs to fix more broken bits * Add missing docs * fmt * allow larger result errs for now * Add missing alloc imports in subxt-core * 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 * clippy
