Adding the ability to compute 2-m min/max T & RH over the previous 24 hour period

[EdwardColon-NOAA]

Description

Within the context of RTMA, a key feature currently in production is the calculation of 2-m min/max temperature and relative humidity over the previous day. This feature would be beneficial for the 3D-RTMA as well.

Solution

The source code used to build executables needed to compute the min/max temperature and relative humidity in operations has been updated for the 3D-RTMA and has been integrated into the rrfs_utl directory structure.

Alternatives (optional)

None

This pull request is linked to a second pull request with will be submitted in the regional workflow branch which will build the min/max T & RH executables directly from the rrfs_utl source codes.
