    Description

      To allow ingest of phosim-simulated data while using lsstCam mapper we suggest to add  controller = 'H'.  This is to guarantee unique obsid values for phosim data (Tim Jennes's comment).  If this is done, currently the translator returns (using  obs_lsst version w.2020.48-1-gf0a7a3e )

      translate_header.py -p lsst.obs.lsst.translators MC_H_20000217_000032_R00_SW0.fits 
       
      Analyzing MC_H_20000217_000032_R00_SW0.fits...
      ValueError("Supplied controller, 'H' is neither 'O' nor 'C'")
      

      An update is needed to allow for controller = 'H' . It affects the  `exposure_id` method in https://github.com/lsst/obs_lsst/blob/master/python/lsst/obs/lsst/translators/lsst.py  

      It doesn't clash with other definitions https://confluence.lsstcorp.org/display/SYSENG/Image+naming+and+visit+definition+conventions (K-T Lim's comment).

            Generally we only assign one code reviewer. https://developer.lsst.io/work/flow.html#assign-a-reviewer

            The changes in the PR look good. An additional comment would be welcomed, as suggested in the PR. Ideally there would be a test as well; it looks like there may be some "controller = C" tests that could be emulated like https://github.com/lsst/obs_lsst/blob/master/tests/test_parsetask.py#L110-L132

            Also make sure you test this in CI: https://developer.lsst.io/work/flow.html#testing-with-jenkins

            And the typical process for multiple reviewers is for each reviewer to remove their name from the reviewers list when done; the last sets the Jira issue to "Review Complete" state. Accordingly, I am removing myself.

            Looks reasonable. Thanks for adding the test.
