Pioreactor

- improve reliability of self-test `test_REF_is_in_correct_position`
- improve the early OD reading signal behaviour.
- new API on jobs for `job_name` (class level now)

- The SQL triggers were not added to the images, so `pioreactor_unit_activity_data` was never populated. This is fixed.
- New web server backend. Went from js/Node to python (Flask)/lighttp.
- Export datasets now cleans up its csvs.

- Bug fixes

- temperature automation `silent` is now `only_record_temperature`.
- using new official RPi image from 2022-09-06 as a source image.
- Bug fixes

- added subcommands `display_current`, `change_current`, `list` to pump calibration
- Pump calibration follows the same format as LED calibrations. Current calibrations can be replaced with previous.
- Adding calibration curves to calibrations' `display_current`
- `pio run export_experiment_data` now has an flag argument to partition csvs by unit.
- pump calibrations are now keyed by `media`, `waste`, `alt_media` in storage `current_pump_calibrations`
- Dosing automation have access to `latest_od` now.
- Bump plotext.

- `local_ac_hz` is now optional
- maybe fix bugs for local AP
