check for pressure information at init time and disable the pressure plugin if it is not present

per the discussion in !82 (merged) this may be a better approach for openSUSE users

As of the submitting of this PR the code is untested - I pretty much just hacked it together - ill try and get to that soon to verify it builds and runs.

Things I would like to improve:

• split the new print statement into two parts, one standard "what went wrong" part that's printed for everyone, and a "how to fix it" part for openSUSE users (ideally behind a conditional compile flag for openSUSE users).

CC @noee would love your help testing this once I verify it compiles! Thanks so much for letting me know about this log spamming bug!
