Replaces parameters in a claims using the input mapping functions.
This can be used to e.g. map the time parameter in a claim from `Date` to `Time`, or
to map the asset type parameter from an abstract `Text` to a concrete `InstrumentKey`.
The functor map operation _and_ also map any parameters to keys.
For example, could map the param "spot" to an ISIN code "GB123456789".
Also contra-maps time parameter, i.e. from relative time values to absolute ones.
@ mapParams identity = bimap
Parties mapped by a specific key (or context).
The textual key is the "context" which describes the value set of parties.
This allows processes to add/remove parties for their specific purpose, without affecting others.
