Add QC filters for radar reflectivity to align with GSI

[SamuelDegelia-NOAA]

Description

This PR adds several observation-space filters for radar reflectivity in UFO that align with the quality control logic currently used in GSI. These new filters include:

• Height check to remove any observations where height AGL > 10 km (corresponding GSI code)
• Observation error inflation to 10 dBZ in regions of precipitation (corresponding GSI code)
• Initial gross error check to inflate observation errors to omb/4.0 where error ratio > 4 (corresponding GSI code)
• Final gross error check to reject observations where error ratio > 8 (corresponding GSI code)

After making these updates, the fv3-jedi increments for Hybrid 3DEnVar are very close to GSI (see slide 35 here). The final observation counts are also very similar. Here are counts for the 2024050601 cycle from rrfs-workflow:

GSI: 192,328 read, 176,509 pass
JEDI: 192,039 read, 176,241 pass

The different number of obs being read in is due to the built in domain check in GSI (here). Those differences get propagated into the ~250 ob difference for those passing QC.

Thanks for @daviddowellNOAA for pointing me to the updated error inflation codes in GSI! Also thanks to @delippi for some ideas on how to add the filters.
