Major Refactoring and JSONRPC
Remove stdstreams parser in favor of JSONRPC, which is much easier to use. Refactor utils into module functions. Remove Command-related modules due to JSONRPC removing the need for them, except executor, renamed to snowflakeapi, an abstraction class for easy JSONRPC usage.
