`Result.plot_corner` should still work OOTB if I move the hdf5 file

Tried to use plot_corner on a result file that I loaded in after moving it over from the cluster to my local machine. The issue is that the outdir attribute still points to the old location. I think this should be overwritten in read_in_result

Traceback (most recent call last):
