This PR adds support for the particulate_matter sensor type as proposed in #129.

@mweinelt I would also ask you to provide feedback as well since you requested this feature in the first place.

I think PM1, PM2.5, PM4 and PM10 are a good sample to start with. Will try to implement these in our Space API shortly.

I did some online research and found that "PM4.25" seems to be an industry standard. Are you sure "PM4" isn't just an abbreviation used by your sensor?

The actual question would be if statically defined PM sizes are adequate.
