Save cross_corr info in output files

[ubdbra001]

Currently cross correlation info file is saved at the end of processing, and only the most recent values are placed in the file.

• Will be for 'flow_glob' mode
  • But can have empty columns for other flow modes to ensure consistency
• Currently, cross_corr only runs once per X mins, so values will be repeated until cross_corr re-run
  • Future update will include running cross_corr on every loop

Additional columns:

• ica_gap
• lag_frames
• lag

Fixing this issue can also include removing save_processing_params() from PyplisWorker: https://github.com/twVolc/PyCamPermanent/blob/f3d72918b0a0a167eebd2e610dfff9cdec08be17/pycam/so2_camera_processor.py#L3868-L3901
