BREAKING CHANGE: The analyzer requires 'ffmpeg'. The 'rgain3' python package and it's system dependencies can be removed.
Some initial work on modernizing the analyzer app. This replace any custom logger or `logging` based logger with the logging tools from `libretime_shared.logging` and `loguru`.
- rename cli to main
- use pathlib in setup.py
- add api-client and shared package as dev deps
- rework main entrypoint cli to use click and shared helpers
- remove unused imports
- replace logging with logger
- rework analyzer app using shared abstract app
- move analyzer log path to systemd service
- change analyzer working dir
BREAKING CHANGE: The analyzer cli has been reworked and uses new flags / environnement variables for configuration.
`--debug` flag becomes `--log-level <level>`
`--rmq-config-file` flag becomes `--config <filepath>`
`--http-retry-queue-file` flag becomes `--retry-queue-filepath`.
`retry-queue-filepath` default value changed from `/tmp/airtime_analyzer_http_retries` to `retry_queue` in the working dir.
`LIBRETIME_CONF_DIR` environnement variable replaced by `LIBRETIME_CONFIG_FILEPATH`.
BREAKING CHANGE: When running analyzer as a systemd service, the working directory is now /var/lib/libretime/analyzer.
