Made a mess of #2084 in a rebase, easier to make a new PR.
Problem
It would be great to import RPC response parsing code without relying on the request-building code - it it not uncommon to want one without the other. Pulling out the response-parsing code allows you to avoid the jsonrpc-core and reqwest dependencies, which are very heavy.
Summary of Changes
Move
solana_rpc_client_api::response
(except for theRpcResult
alias) to its own crate, and re-export for backwards compatibility.
