Detect the sector size of the target device, then select the right
format from the stream metadata based on that.

Closes: #201

OK so coreos/coreos-assembler#1312 enhances kola testiso for testing metal4k image installs. Will hook it up here and in the pipeline too afterwards, though it doesn't actually test the new codepath here since we're not doing a stream install. We could work on mocking that though... not sure if we should block on this. I did test this code on the current stable stream metadata though and it did the right thing. :)

Will address review comments tomorrow!

This makes it easier for the user to tell that the right image is being
downloaded for the target device.
