Static Decoding of Signed Extensions: Simple Approach (#1235)

* skeleton commit

* signed extension decoding

* fix some minor things

* make api more similar to Extrinsics

* defer decoding of signed extensions

* fix byte slices

* add test for nonce signed extension

* adjust test and extend for tip

* clippy

* support both  ChargeTransactionPayment and ChargeAssetTxPayment

* address PR comments

* Extend lifetimes, expose pub structs, remove as_type

* add signed extensions to block subscribing example

* add Decoded type

* fix merging bug and tests

* add decoded type in CustomSignedExtension

* fix minor issues, extend test

* cargo fmt differences

* remove the `decoded` function

* new as_signed_extra fn, do not expose as_type anymore

* fix Result-Option order, simplify obtaining Nonce

* tx: Remove `wait_for_in_block` helper method (#1237)
