Re: [mediacapture-image] Document OverConstrainedError for PTZ in explainer (#229)

It seems there is consensus to make the PTZ constraints be ideal only.
The easiest path is to neuter any PTZ required constraint.
getUserMedia step 6.3.3 is cleaning up the constraints given to getUserMedia before proceeding with selecting the settings.

We could add a step in getUserMedia algorithm that would further remove some required constraints, for instance any required constraint whose name is not in a well defined list. This list could of course be extended by specifications defining new constraints. PTZ constraints would not be in that list.
