allow setting .cache location via environment variable #1029

On some HPCs mriqc fails because /home/bidsapp is located on a readonly filesystem (see https://neurostars.org/t/mriqc-v0-15-2-read-only-error-on-hpc-cluster-oserror-errno-30-read-only-file-system-home-bidsapp-cache-mriqc/7005).

While the solution mentioned in the above works it requires the user to have control over the singularity call, which isn't always possible, for instance in flywheel or XNAT gears/modules.

It would be convenient if mriqc used an environment variable similar to (https://numba.readthedocs.io/en/stable/reference/envvars.html?highlight=ENVIRONMENT#envvar-NUMBA_CACHE_DIR) to allow user control over where this written.

Best,
