fix(revit): CNX-394 better reference point cache invalidation

[clairekuang]

Reference point pr was caching the setting, and invalidating cached objects only if setting has changed. Since it is the transform that determines whether or not we need to reconvert objects, now we are tracking the reference point transform instead of the setting enum . This is because users can change the reference point between send operations, resulting in a changed transform even though the reference point enum remains the same.

• Note: also fixes cache invalidation for objects that need to be unpacked, issue: https://linear.app/speckle/issue/CNX-394/revit-object-invalidation-skipping-some-objects
