Roll out exported symbols in index.ts

[webmaster128]

It would be great to have all exported symbols of the package visible in one file. For this, can we make the *s in

CosmWasmJS/src/index.ts

Lines 1 to 13 in a2a013a

	/**
	* Exporting all the defined CosmJS symbols
	*/
	export * from "./amino";
	export * from "./cosmwasm-stargate";
	export * from "./crypto";
	export * from "./encoding";
	export * from "./faucet-client";
	export * from "./ledger-amino";
	export * from "./math";
	export * from "./proto-signing";
	export * from "./stargate";
	export * from "./utils";

explicit?

Maybe we should remove all the .ts files that only re-export CosmJS types and do that in the main index file directly.
