feat(tools/when): support more timestamps with better merging logic HEAD r/8093 canon

Adds a FieldSet type which defines which parts of a timestamp to merge into
another in a new `mergeTime` function.

With this two timestamps can be merged granularly, enabling more queries like
`Sep 03 18:00` to return useful results (e.g., in this case, in the current year
and location).
