Remove goto statements from chgres_cube (#775)
The WAM option was using the NRLMSISE-00 library, which contains numerous 'goto' statements. That library was replaced with the latest NRLMSIS 2.1 library, which does not use 'goto' statements and is also a welcome improvement in initializing the upper atmosphere. The new library included a unit test, which was added to run under Github actions. Fixes #759.

| !!! NRLMSIS 2.1: | ||
| !!! Neutral atmosphere empirical model from the surface to lower exosphere | ||
| !!! =========================================================================== | ||
| !!! | ||
| !!! MSISCALC: Interface with re-ordered input arguments and output arrays. | ||
| ! | ||
| ! PREREQUISITES: | ||
| ! Must first run MSISINIT to load parameters and set switches. The | ||
| ! MSISCALC subroutine checks for initialization and does a default | ||
| ! initialization if necessary. This self-initialization will be removed | ||
| ! in future versions. | ||
| ! | ||
| ! CALLING SEQUENCE: | ||
| ! CALL MSISCALC(DAY, UTSEC, Z, LAT, LON, SFLUXAVG, SFLUX, AP, TN, DN, [TEX]) | ||
| ! | ||
| ! INPUT VARIABLES: | ||
| ! DAY Day of year (1.0 to 365.0 or 366.0) | ||
| ! UTSEC Universal time (seconds) | ||
| ! Z Geodetic altitude (km) (default) or Geopotential height (km) | ||
| ! LAT Geodetic latitude (deg) | ||
| ! LON Geodetic longitude (deg) | ||
| ! SFLUXAVG 81 day average, centered on input time, of F10.7 solar | ||
| ! activity index | ||
| ! SFLUX Daily F10.7 for previous day | ||
| ! AP Geomagnetic activity index array: | ||
| ! (1) Daily Ap | ||
| ! (2) 3 hr ap index for current time | ||
| ! (3) 3 hr ap index for 3 hrs before current time | ||
| ! (4) 3 hr ap index for 6 hrs before current time | ||
| ! (5) 3 hr ap index for 9 hrs before current time | ||
| ! (6) Average of eight 3 hr ap indices from 12 to 33 hrs | ||
| ! prior to current time | ||
| ! (7) Average of eight 3 hr ap indices from 36 to 57 hrs | ||
| ! prior to current time | ||
| ! AP(2:7) are only used when switch_legacy(9) = -1.0 in MSISINIT | ||
| ! | ||
| ! NOTES ON INPUT VARIABLES: | ||
| ! - The day-of-year dependence of the model only uses the DAY argument. If | ||
| ! a continuous day-of-year dependence is desired, this argument should | ||
| ! include the fractional day (e.g., DAY = <day of year> + UTSEC/86400.0 | ||
| ! - If lzalt_type = .true. (default) in the MSISINIT call, then Z is | ||
| ! treated as geodetic altitude. | ||
| ! If lzalt_type = .false., then Z is treated as geopotential height. | ||
| ! - F107 and F107A values are the 10.7 cm radio flux at the Sun-Earth | ||
| ! distance, not the radio flux at 1 AU. | ||
| ! | ||
| ! OUTPUT VARIABLES: | ||
| ! TN Temperature at altitude (K) | ||
| ! DN(1) Total mass density (kg/m3) | ||
| ! DN(2) N2 number density (m-3) | ||
| ! DN(3) O2 number density (m-3) | ||
| ! DN(4) O number density (m-3) | ||
| ! DN(5) He number density (m-3) | ||
| ! DN(6) H number density (m-3) | ||
| ! DN(7) Ar number density (m-3) | ||
| ! DN(8) N number density (m-3) | ||
| ! DN(9) Anomalous oxygen number density (m-3) | ||
| ! DN(10) NO number density (m-3) | ||
| ! TEX Exospheric temperature (K) (optional argument) | ||
| ! | ||
| ! NOTES ON OUTPUT VARIABLES: | ||
| ! - Missing density values are returned as 9.999e-38 | ||
| ! - Species included in mass density calculation are set in MSISINIT | ||
