Create a Parsec Rust Client

[hug-dev]

Repository name will be parsec-client-rust. The Rust client will provide different abstraction layers as modules, the lowest one simply exposing methods for all the operations in the interface with all the parameters.
A large part of the Rust client could be taken from the current test client.

If this client is to be used in the future as the base for the test client, it's important that the Rust client exposes all "intermediary" levels of access.
E.g. I believe the core/minimal client functionality would be at operation-level, allowing a user to send an operation by providing all parameters. However, for test we'd need to potentially send malformed requests, or just random bytes, to the socket. This shouldn't be something exposed by any client library inteded for users, though.

Closing this as all issues pertaining to the client are in the repo mentioned by @hug-dev above.
