Re: [pointerevents] Multi-pen support and persistent pointerId (#353)

Hey @patrickhlauke

I think there is already some context around the lifetime of the `pointerId` in the NOTE section under `pointerId`. Our current line of thinking is that each pen would be mapped to an index, starting with 1, and each time that pen generated a PE the `pointerId` would be the same. If the document is closed or refreshed, the `pointerId` can be different for each pen. Behind the scenes, the implementation would map the Pen hardware ID to this index and keep track of it, limiting exposure of the unique Pen hardware ID from fingerprinting.
