desi_tile_redshifts --run_zqso option

[sbailey]

This PR

1. adds a desi_tile_redshifts --run_zqso option to run make_zqso_files after running redshifts
2. pipeline automatically includes --run_zqso for cumulative redshifts but not other groupings
3. adds copyprod --night YEARMMDD option, which can include a wildcard, like copyprod --night 202106\* ... (unreleated to --run_zqso, but used for testing).

I have tested (1) and (3), but not (2).

Outputs of desi_tile_redshifts -n 20210601 -t 1207 -g cumulative --run_zqso are in /global/cfs/cdirs/desi/users/sjbailey/spectro/redux/zqso/tiles/cumulative/1207/20210601

@akremin please check pipeline logic; @geordie666 and/or @eleanorlyke please check zqso outputs.

Coverage decreased (-0.004%) to 27.321% when pulling da5a417 on zqso into 84e46e8 on master.

From the pipeline perspective: the logic looks good.
It's so minor that I'm not terribly worried about testing it, but I will run a test anyway and report back.

I tested with desi_daily_proc_manager --override-night=20210601 --dry-run-level=1 in a test SPECPROD to verify that it works.

The cumulative redshift scripts produced by the pipeline had the new zqso code.

It worked as expected.

[geordie666]

The zqso outputs look good. I did a mini-run and achieved the same results. The necessary columns are all there, the files all have the expected 500 rows.

As a final check, for objects with IS_QSO_QN==1 and ZWARN==0 the redshift agreement between redrock and QN is excellent. So, this all checks out.
