Returns the {@link Address} to an offset that is relative to the controlling
GoModuledata's text value.

@param ptrInModule the address of the structure that contains the offset that needs to be
calculated.  The containing-structure's address is important because it indicates which
GoModuledata is the 'parent' 
@param off offset
@return {@link Address}, or null if offset was special value -1
