Release v2.2.0

feat: Improve retry and exception handling in the SDK clients (#171)

# Overview

The retry mechanism was incorrectly configured, resulting in capturing
and retrying on errors it shouldn't retry on, e.g.
`asyncio.CancelledError` or `asyncio.TimeoutError`. Instead of a
negative filter when using `tenacity`'s `retry` decorator, i.e.
`retry_if_not_exception_type((CompassClientError,))`, which captured a
lot more exceptions than we originally intended, we now specifically
list the exceptions that we know we want to retry on, or otherwise let
the error bubble.

This PR also improves the exception hierarchy by introducing a few new
exceptions to help us better communicate errors to the clients without
having to bubble or wrap httpx exceptions. Specifically, we are
introducing:

- CompassNetworkError
- CompassServerError
- CompassTimeoutError

As part of this PR, the `utils.py` module were refactored into multiple
files to avoid having a pile of utility functions dumped in a single
file.
