Option to disable harmonic flagging

[chiamintan]

The current riptide pipeline set up have harmonic flagging being run all the time. For my case of having a large number of candidates (10000+) with little candidates being flagged (<100), it is not useful to take ~1 hour to run the flagging. So I think there should be an option to disable the harmonic flagging process.

Hi @chiamintan,

This would be a good addition. There is no way to skip harmonic flagging at the moment. Currently, the harmonic filter parameters are set like so in the config file:

riptide/riptide/pipeline/config/example.yaml

Lines 177 to 181 in 90f2386

	harmonic_flagging:
	denom_max: 100
	phase_distance_max: 1.0
	dm_distance_max: 3.0
	snr_distance_max: 3.0

I suggest adding the following key and adding a check for it in the flag_harmonics method of the pipeline:

harmonic_flagging:
  # Skip harmonic flagging if false
  enable: true

I can do this easily when I have an opening (soon-ish), but it could also be a good exercise for a student in your group to get more familiar with the code and get some git / GitHub MR / Python experience. Your pick.
