Make `area` optional for spaceranger v4

[mjseignon]

This error pops up during samplesheet validation.

/sc/service/analysis/develop/nf-tenx/bin/check_samplesheet.py 25V1-25V2_Visium.yml /dev/null
ERROR: Samplesheet record 1 -> Specified assay 'CytAssist Gene Expression' must have key 'area'!

So basically:

• if "manual_alignment.json" is not present
  • require slide serial & area
• else
  • slide serial & area are optional
    ?

[mjseignon]

Regardless of alignment status, slide serial & area are optional since this metadata is collected for all cytassist images we captured with "cytassistInstrumentSoftwareVersion":"2.0.1.3", starting March 2024.
As you mentioned in teams. We can have a logic that makes them optional.
Maybe starting at v3+
