[mediacapture-depth] Setting unit in constraints

dontcallmedom has just created a new issue for 
https://github.com/w3c/mediacapture-depth:

== Setting unit in constraints ==
The way constraints for mediastreamtrack have been defined is to allow
 browser-mediated negotiations of allowable ranges in which an 
application can operate on the said track.

Using this to indicate the unit of the reported values seems a poor 
application of that concept, since there is no particular reason why 
one would negotiate between meters and milimeters (or at least, I 
can't see what reason); in general, I'm not sure there is any value in
 saving the developers from a division or multiplication by a fixed 
number (1000) here.
