Cleaned up the threading logic around startup/shutdown to reduce CPU and memory leaks
- Added validation checks for the API Key ID and API Key to help prevent issues logging in Fixes #47
- Cleaned up the thread and process tracking to ensure that we release threads when they're done
- Only allow one running purge thread per camera Fixes #40
- Added timeouts to all the thread
.join()s to ensure we don't hang waiting for threads to die off - Increased the buffer site for the pipe reads to reduce CPU load
- Consistently swallow ValueError, AttributeError, RuntimeError, and FileNotFound errors so sub-processes and threads terminate correctly
Note: v3.12.2 was everything above, but missing the change notes, oops.
