Merge #2713

2713: Add map functions for the node-to-client protocol Client types r=dcoutts a=dcoutts

That is, for the wrapper types of the client side of all the
node-to-client protocols, specifically the types ChainSyncClient,
LocalStateQueryClient and LocalTxSubmissionClient.
    
These are useful for the cardano-api where we want to present the
protocol handlers using one set of types, but then execute them at the
proper wire types.
