Ts sharing coders

[TimSheard]

Extends the Coders library to handle Sharing on the decode side.
Adds some DecShareCBOR instances as described in issue #3486 using the new tools

Began to address the problems described in issue #4192, about serializing CompactForm MultiAsset, without affecting backward compatibility.

A large part of the changes have to do with the following changes

1. replacing Ann with Pure
2. replacing (<!*) with (<!>)

The original operators Ann and (<!*) had to do the the Annotator type, but the ones have been generalized to work with any Applicative functor. Including the monad (StateT (Share b) (Decoder s) b) which is the basis for Sharing.
