minor fixes to avoid singularity/apptainer issue for get_delay_dir

I managed to get split-directions working with toil-cwl-runner, but had to make a fix to the get_delay_cal_direction.cwl step, and the get_delay_dir.py script. The issue was that singuarity/apptainer prints a harmless warning on some systems which is stdout. On line 11 of get_delay_cal_direction.cwl, the stdout gets dumped in delay_dir.csv. The next step reads this file expecting to find source,ra,dec but then fails because the first line is the singularity/apptainer warning.

The fix I implemented and tested was:

modify get_delay_cal_direction.cwl:

• update line 11 to be

stdout: get_delay-dir.txt

modify get_delay_dir.py:

• update lines 28-29 to the following:

with open('delay_dir.csv','w') as f:

f.write("Source_id,RA,DEC\n")

f.write("DelayCal,{:f},{:f}".format(ra,dec))

This ensures that the delay_dir.csv file only ever contains what the next step expects.

I was going to fork and create a merge request, but it seems I do not have permissions to do this.
