Add AccuracyRank and ValuePrecision schema items, bump schema rev

[StokesMIDE]

This change doesn't break backwards compatibility when parsing the data, so maybe DocTypeReadVersion should not be incremented.

Fair point for the two tags added in this commit, but this bump will coincide with new ChannelParser/ChannelFormat behavior that will break current parsers, I thought you suggested emitting a future rev would prompt the user to upgrade ahead of the crash (I assume it will still fail, but at least they'll know why).

Fair enough, keep them both incremented. The difference between DocTypeVersion and DocTypeReadVersion (and when you would change one and not the other) seems a little vague.
