GAMLN and REFL10CM for NTU microphysics

[tzuchin12]

TYPE : Enhancement

KEYWORDS : NTU microphysics, LOG_GAMMA, REFL_10CM

SOURCE : Tzu-Chin Tsai, Taiwan Central Weather Administration (CWA)

DESCRIPTION OF CHANGES :

1. Replaced the custom GAMLN function with the intrinsic LOG_GAMMA function. The replacement with LOG_GAMMA requires Fortran 2008 support, which is available in the supported compilers for current WRF releases.
2. Added diagnostic outputs for horizontal radar reflectivity (REFL_10CM) and hydrometeor effective radius (re_cloud, re_ice, and re_snow).

LIST OF MODIFIED FILES :

1. phys/module_mp_ntu.F
2. phys/module_microphysics_driver.F

TESTS CONDUCTED :
Successfully compiled WRF version 4.8.0 and completed the idealized 2D em_squall2d_x simulation without errors.

RELEASE NOTE :

1. Updated the NTU microphysics scheme by replacing the custom GAMLN function with the intrinsic LOG_GAMMA function.
2. Added diagnostic outputs for REFL_10CM, re_cloud, re_ice, and re_snow.

@tzuchin12 The compilation failed for all the runs. A log file is attached below. It looks like your base code isn't standard, with packages like NSSL_2MOMCCN, NSSL_2MOMG, not found in the standard version.

Sorry, the module_microphysics_driver.F has been updated to the latest version.
