'any'-typed json objects

[dynst]

Subissue of #1750

There's a lot of any in the codebase, especially for JSON/protobuf stuff.

cosmjs/packages/amino/src/pubkeys.ts

Lines 1 to 7 in ca243f5

	export interface Pubkey {
	// type is one of the strings defined in pubkeyType
	// I don't use a string literal union here as that makes trouble with json test data:
	// https://github.com/cosmos/cosmjs/pull/44#pullrequestreview-353280504
	readonly type: string;
	readonly value: any;
	}

cosmjs/packages/tendermint-rpc/src/tendermint34/responses.ts

Lines 239 to 245 in ca243f5

	/**
	* We lost track on how the evidence structure actually looks like.
	* This is any now and passed to the caller untouched.
	*
	* See also https://github.com/cosmos/cosmjs/issues/980.
	*/
	export type Evidence = any;

And the parsing code looks weirdly structured and scattered around. Simple assertObject utility functions are defined 4 different times, copypasted around. Fields are checked piecemeal instead of a single pass validation to cast unknown or JsonValue to SpecificType - objects get casted as a class before actually confirming all mandatory fields are there.

cosmjs/packages/tendermint-rpc/src/tendermint34/adaptor/responses.ts

Lines 881 to 883 in ca243f5

	public static decodeGenesis(response: JsonRpcSuccessResponse): responses.GenesisResponse {
	return decodeGenesis(assertObject((response.result as GenesisResult).genesis));
	}

One of these could be useful:
