This file contains overloads of the serialize functions for array2d object
for the case where they contain simple 8bit POD pixel types. In these
cases we can perform a much faster serialization by writing data in chunks
instead of one pixel at a time (this avoids a lot of function call overhead
inside the iostreams).
