Add ITR label fields and read ITR coordinates from vector annotation BED #47

Description

@etal

To provide more fine-grained read classifications, LAAVA will need the coordinates of each ITR, not just the overall vector region (status quo). The two ITRs (left and right, or WT-ITR and mITR) are not necessarily the same size, and are not necessarily labeled with the same strings in every vector design that the annotation BED is derived from.

Tasks:

  • Add 2 more input fields for the ITR names as they will appear in the annotation BED file, e.g. itr_l_label and itr_r_label, or itr_label_1 and itr_label_2.
  • Read those labels from the annotation.
  • Use those labels in the Python scripts for classification.

TBD / later:

  • The outer coordinates of the two ITRs should be identical to the annotated vector region -- therefore, having these two annotations is redundant with the single "vector" annotation that's currently required. Consider dropping the requirement for a "vector" label in the annotation BED, and use the ITR coordinates to calculate the "vector" coordinates instead.
  • Keep the "vector" option as a legacy code path that omits ITR-dependent classifications, or strictly require ITR labels right away?

Blocks #42. Easier if #19 is done first.
