Rewrite remote HDD functionality

The remote HDD function is currently unstable, largely do to the low-level nature and my lazy implementation of TCP/IP sockets. After the switch to `asyncio` (see #2), this should be rewritten using the `websockets` module.

The issue mentions switching to asyncio (issue #2) and using the websockets module. Look for the current remote HDD implementation, likely involving TCP/IP sockets. Understand the existing codebase structure, then rewrite the functionality using websockets after the asyncio transition is complete. Check for any related tests or examples of websockets usage in the project.
