Previously we linked against the dynamic libtiff library, but this
didn't work when running the fuzzers.
This time, actually tested by launching
python infra/helper.py run_fuzzer $PROJECT_NAME proj_crs_to_crs_fuzzer
proj.4 is standard UNIX filter function which converts
geographic longitude and latitude coordinates into cartesian
coordinates (and vice versa), and it is a C API for software
developers to include coordinate transformation in their own
software.
See http://proj4.org/
Note: it is used by the GDAL library, already in OSS-Fuzz.
