Separate multipliers per claimed denom (#971)
* move multipliers to their own file

* add multipliers per denom to MsgClaimHardReward

* claim with multipliers per denom for hard claims

* remove unused error

* add multipliers per denom to params
connect to to hard claiming

* temporary fix migration

* update usdx claiming for new multiplier params

* claim with multipliers per denom for delegator

* claim with multipliers per denom for swap rewards

* tidy up multiplier name validation

* rename new multipliers field in params

* remove old multpliers from params

* clear up various TODOs

* add tags to new structs

* remove dead code
