Description

Don't actually merge this anywhere. It's just a record of stuff to make psi work.

• the getkw bit allows sequential pcmsolver calcs w/o input keyword redefined error. already in help the reimport problem #184
• the abc squashes some warnings that imperil py39
• the tmpnam is new and avoids intermittent errors running multiple pcm tests at the same time. this probably breaks the default of loadCavity, but that's not being used anyway :-) (at least in v1.2.1) EDIT: indeed, this breaks your from_file tests
