* Checks whether cell contains any tag with type as VISIBILITY_TAG_TYPE. This
* tag type is reserved and should not be explicitly set by user.

* @param pair - an optional pair of type <Boolean, Tag> which would be reused
* if already set and new one will be created if null is passed
* @return a pair<Boolean, Tag> - if the boolean is false then it indicates
* that the cell has a RESERVERD_VIS_TAG and with boolean as true, not
* null tag indicates that a string modified tag was found.
