Updated cryo-SIM processing logic

[tieneupin]

• Simplify the pattern matching logic used to identify cryo-SIM contexts and to trigger processing.
  • When establishing the cryo-SIM workflow, it was understood that only files with stems ending in "_BR_FL", "_BFR_FL", "_GR_FL", or "_GFR_FL" would require processing. However, it turns out that this is very much not the case: A single colour channel could be collected, and users would end the file with "{color}_again_FL" if this was a repeat of a previous collection.
  • Given that we provide the OTF files for all the wavelengths to the PySIMRecon processing service, and that PySIMRecon is able to parse the file metadata to determine the colour channels to use, we don't need to look for specific colour combinations anymore, and can just trigger processing on files ending with "_FL" instead.
• Move OTF file lookup logic into a cached function.
  • Unless a new OTF directory is uploaded during the visit, all PySIMRecon processing requests will be carried out using the same OTF files.
  • Performing this file lookup anew for every new raw data file is thus needless computational expense, and having this logic moved out into a cached function should optimise for computation.
