Standalone and typed re-write of Parity Signer's parser crate.

We've been asked by community to do this for a long time, now that we've got some time free - here you go.

This crate could be used to programmatically find entries in chain data - calls, storage, pretty much anything that is described by metadata. Example usage minimal working code can be seen in [QRUCIAL project](https://github.com/Qrucial/QRUCIAL-DAO/blob/main/exosysd/src/main.rs) where an event is fetched from a chain

And of course with the use of `.card()` call this crate could be used as a replacement for Parity Signer's built-in parser with certain modifications (list of displayed cards would have to be changed). We intend to use this crate in future projects like [Kampela](https://polkadot.polkassembly.io/post/1227).

Extensions are parsed automatically as well. Support of pre-V14 metadata was dropped deliberately (at least for the time being).
