NON DARCY test cases

[millerta]

George sent Liquid and Gas test directories for darcy and non-darcy pump test simulations.

As of Feb 20 the new nondarcy code merged with master passes Win and linux verification tests:
/project/eesdev/FEHM/VV_TESTS
drwxrwsr-x 73 tamiller sft 12288 Feb 7 15:25 VERIFICATION_V3.3.0lnx_V3.6_jan2025
drwxrwsr-x 100 xhuang sft 12288 Feb 7 17:30 VERIFICATION_V3.4win_v3.6_clean_XH02072025

There are some format differences mostly with 1.0 and 10.0 having more zeros for Time values.

All fehmpytests pass except for cden which has a fix to pres .his files
The compare files were updated to these corrected files.

NONDARCY static-multi*_presVAP.his now has values. Release V3.6.2 was missing values.
NONDARCY static-multi*_presWAT.his now has single line time increments. Release V3.6.2 had double lines.

The rest of the .his files MATCH release V3.6.2 except format with 000s:

Release has 7 0s for time
99.0447450 0.00000000 0.00000000 0.00000000 0.00000000 0.00000000

Merged Windows and Linux codes were run on George's LIQ and GAS tests.
George's tests were all run in the same output directory using files in his input directories.
presWAT.his files were saved with name indicating which run created it.
This made it hard to run a test and compare so I split all tests into their own directory for easier examination of results.
I assume input files for all runs were the same except for the use of macro "ndar" settings.

Everything looks good except for Bad Values in in output report file:

non_darcy_2D_gas2_gonly.out under Nodal Information
