Re: [ambient-light] RFC: Mandate that illuminance readings be rounded; require threshold value check. (#77)

My initial impression is this looks good!

>It is not clear if "at least 50lx" makes sense or if we should mandate 50lx specifically in the values above.

AFAICT, the "at least 50lx" threshold was informed by research conducted in this group with [results](https://docs.google.com/spreadsheets/d/1vUojkaaif6AmftQmtqra1w9Z7CH00Cn9pb0Ci6v5_Jk/edit#gid=0) collected using a setup described at https://github.com/w3c/ambient-light/issues/13#issuecomment-302393458.

Optimally we'd link to this data in the spec so that privacy researchers can review the test setup and data easily and we can adjust this mitigation if new information is brought to our attention. Revise as needed.

Rather than linking to a Google sheet, I'd prefer to see this data exported into an appendix in the spec, or alternatively convert the sheet into a markdown file stored in this repo.

Again, I'll lean on @sandandsnow and other PING participants for privacy experts' perspective.
