timeBoundary variant for extended gauge field

Parameters

idx	extended field linear index
X	the gauge field dimensions
R	the radii dimenions of the extended region
tBoundary	the boundary condition
isFirstTimeSlice	if we're on the first time slice of nodes
isLastTimeSlide	if we're on the last time slice of nodes
ghostExchange	if the field is extended or not (determines indexing type)
