Replace the oblique process(T) overloads for integer types with
explicit process_le/be(T) methods that would interpret the given integer
as a stream of bytes using the corresponding endiannes.
For instance
process_le(0x11223344) would treat this integer as the following array of bytes:
{0x44, 0x33, 0x22, 0x11}.
process_be(0x11223344) on the other hand would treat this integer as if it's
{0x11, 0x22, 0x33, 0x44}.
