This is a sub-issue of #3120.

Describe the Sub-Issue

Re-gridding has been identified as a bottleneck when processing RRFS data. Use OpenMP to parallelize the processing in the vx_regrid library to improve runtime efficiency. And since re-gridding applies to many MET tools, move the call to init_openmp() to initialize OpenMP from specific applications into the common main() function in vx_util/main.cc.
