Add a utility function to get query responses to Decimal.

import {Tendermint34Client} from "@cosmjs/tendermint-rpc";
import {createProtobufRpcClient, QueryClient} from "@cosmjs/stargate";
import {QueryClientImpl as MintQueryClientImpl} from 'cosmjs-types/cosmos/mint/v1beta1/query';
import { Decimal } from "@cosmjs/math";

       const tendermintClient = await Tendermint34Client.connect("rpc.cosmos....");
       const queryClient = new QueryClient(tendermintClient);
       const rpcClient = createProtobufRpcClient(queryClient);
       const queryService = new MintQueryClientImpl(rpcClient);
       const response = await queryService.Inflation({});
       console.log(response.inflation)

Here response.infaltion returns a uint8array.

        let decoder = new TextDecoder('utf8');
        let decimalString = Decimal.fromAtomics(decoder.decode(response.inflation),18).toString()

Is there another way to do this?

@webmaster128 both decodeCosmosSdkDecFromProto and MintExtension from #969 working fine. decodeCosmosSdkDecFromProto response.toString() giving required result.
