TR “mono” . (TR from TR from with new --correct_areas option)

2.5h on Anvil (single processor)
Weights are good. Row sums error: 7e-16. Conservation error 7e-16
vortex test field l2/max error: 3.6145e-05 4.3881e-04
oRRS18to6 → ne512pg2: status GOOD
~9h to compute overlap map
weights: good. row sum error: 7e-16. Conservation error 7e-16

oRRS18to6 → ne1024pg2: status: GOOD
15.5h on Anvil, using 20GB
weights: good. row sum error: 4e-16. conservation error: 1e15
MBTR “mono”. Status: NOT USABLE
oRRS18to6 → ne256pg2
Weights are good, but 316 MPAS grid points have weight=0. This is incorrect and corrupts other diagnostics.
ESMF “aave”
oRRS18to6 → ne256pg2. Status: GOOD
weights are good. row sum max 8.5e-12. Conservation error 1.5e-11
vortex test field l2/max error: 3.6144e-05 4.3881e-04
oRRS18to6 → ne512pg2. Status: GOOD
weights are good. row sum error 3e-11. conservation error 1e-11

oRRS18to6 → ne1024pg2. Status: NOT USABLE
( /global/project/projectdirs/acme/taylorm/mapping/map_oRRS18to6v3_to_ne1024pg2_aave.nc.BAD )
weights are bad: max 2.6, row sum max 3.0. conservation error 4e-4
same issue with ESMF v8.
Outstanding issues
MBTR FV->FV error - missing source points. It appears MBTR maps have a similar loss of precision as TR maps, but this could be corrupted du to the missing source points.
MBTR SE->SE: montone weights are bad, either NaN or >1
ESMF “aave” and “bilin” maps are good up to ne512pg2, but both produce too large weights with ne1024pg2 (both SE->SE and FV->SE)
AnalyzeMap
request: add min/max of map file frac_a, frac_b data to output
request: check for NaNs when printing weight min/max
for non global (MPAS) source grid, prints tens of thousands of useless consistency warnings
