updated tensorqtl_postprocessor: considering cis-window=0, old files …

[al4225]

Updated tensorqtl_postprocessor:

• Support for cis-window = 0

  • Automatically skips calculate_feature_positions() when cis-window = 0
  • Applies only MAF filtering, avoids errors for QTLs without gene-level annotations (e.g., epigenomic QTLs)

• Compatibility with older file formats (e.g., haQTL)

  • find_common_prefix() updated:

    When a common prefix cannot be determined, fallback logic is used to infer file naming patterns from older versions

• Dynamic molecular trait column handling

  • molecular_trait_object_id is no longer hardcoded
  • New logic allows specifying molecular_id_col dynamically, e.g., using molecular_trait_id for event-level traits like sQTL_SSU
