Make subxt-core ready for publishing (#1508)
* Move Extrinsic decoding things to subxt_core and various tidy-ups * A couple more fixes and fmt * first pass moving tx logic to subxt_core * cargo fmt * fix wasm example * clippy * more clippy * WIP Adding examples and such * Move storage functionality more fully to subxt_core and nice examples for storage and txs * Add example for events * consistify how addresses/payloads are exposed in subxt-core and add runtime API fns * Add runtime API core example * fmt * remove scale-info patch * Add a little to the top level docs * swap args around * clippy * cargo fmt and fix wasm-example * doc fixes * no-std-ise new subxt-core additions * alloc, not core * more no-std fixes * A couple more fixes * Add back extrinsic decode test
