Segmentation fault when LAL_DATA_PATH not set for NRSurrogates

It would be nice for the code not to segfault when the LAL_DATA_PATH is not set (or not set correctly) when trying to evaluate the NRSurrogates. This causes problems downstream. An example output is below,

XLAL Error - NRSur7dq4_Init_LALDATA (LALSimIMRPrecessingNRSur.c:184): Unable to resolve data file NRSur7dq4.h5 in $LAL_DATA_PATH
XLAL Error - NRSur7dq4_Init_LALDATA (LALSimIMRPrecessingNRSur.c:184): I/O error

Segmentation fault
