When using pytest directly, rather than the astropy test runner, quite a few tests are creating files that are not cleaned up after the run. The repo should be left clean of these once the tests are run. I have these after a full run with --remote-data.

	filename.tar

	moc.fits
	tarfile_lightcurves.tar
	target.xml

edit: maybe add a command at the end of the remote-data tests that lists everything that got generated during the run? maybe even test that no new files are hanging around?
