cam6_4_049: History bugfixes

[peverwhee]

Summary

1. Add optional sampled_on_subcycle argument to addfld. If that's true for a field, we don't override the averaging flag to "I" if nhtfrq = 1 (every timestep). This reenables subcycling averages.
2. Check for incompatible duplicates
   • compatible duplicates (flags match) are ok - just take the first one (to keep existing CAM behavior)
   • incompatible duplicates (flags differ) - endrun
3. Remove time_bounds field from instantaneous history files
4. Update default filename for monthly instantaneous files to include full timestamp
5. Update git-fleximod to 0.9.3
6. Improve logging for cam_pio_openfile
7. Update cime to cime6.1.56

I'll just point out that the reason for setting the averaging flag to I when nhtfrq=1 is to get the correct timestamps. If the flag is A then the timestamps are set to midpoint values which is not correct for a single timestep.

@adamrher could you confirm that the addfld calls I've amended represent the full set of fields that are sampled on the subcycle?

Hi @peverwhee, I found some missing addfld calls.

micro_pumas_cam.F90, marcop_driver.F90, microp_aero.F90 all look good. There are a 5 addflds you missed, in stats_init_clubb in clubb_intr.F90. I couldn't figure out how to add a review comment that deep into clubb_intr, but they start at line 5116.

microp_aero.F90 has some dependencies that have addfld calls. These are: ndrop.F90, ndrop_bam.F90, nucleate_ice_cam.F90, hetfrz_classnuc_cam.F90. All addflds in those modules need the sample_on_subcycle flag.

Lastly, the drivers in subcol_SILHS.F90 are called inside the macmic loop if use_subcol_microp=.true. Support for subcolumns is a grey area but it shouldn't be too much work (?) to add sample_on_subcycle to all the addflds in subcol_SILHS.F90.

@adamrher thanks for taking the time to check these! I've added/removed the sampled_on_subcycle arguments as you described.

• stats_init_clubb in clubb_intr.F90 (5 fields)
• ndrop.F90 (all addflds)
• ndrop_bam.F90 (all addflds)
• nucleate_ice_cam.F90 (all addflds)
• hetfrz_classnuc_cam.F90 (all addflds)
• subcol_SILHS.F90 (all addflds)
• REMOVE FROM check_energy.F90 (all addflds)

Looks good.

Curiosity led me to looking into this PR. This is not intended to be a full review, but rather documents a couple of things that I saw.
