Change ~= Operator to be a BBOX Only Test

Description

Right now the assumed behavior of ~= is an index-assisted exact equality check. As a result, unlike all the other GiST operators, it requires a re-check, which means that all our operators end up stuck with a re-check. Having no re-check can lead to odd behavior (#253) when combining the indexed operator call with an un-indexed operator call (#253). It would be better to have all our GiST operators consistently work on bounding boxes only. This will be a slight breaking behavior change.
