main/hwtest: Update to 0.2.0

This adds the first interactive tests for inputs, interactive tests are only run when specifying --interactive/-i

This also adds --export and --verify. The export option will write the test results to an .ini file. The verify option will run the tests and compare it to the saved export and then will show a diff of hardware functionality.

Example on the pinephone:

Running with the main camera disabled with the killswitch:
