Pack the cudaColorSpinorField's ghost zone into contiguous buffers

Parameters

in	The cudaColorSpinorField whose ghost zone we are extracting
dim	The dimension in which we pack
dir	Whether we pack data to be sent forward or backwards or in both directions
parity	The parity of this field
dagger	Whether the operator for which we are applying is the Hermitian conjugate or not
stream	The stream to which the packing kernel will be issued
zeroCopyPack	Whether we are packing to a device buffer or packing straight to host memory
a	Twisted mass parameter (default=0)
b	Twisted mass parameter (Default=0)
