[Olena] #124: Ensure I/O operations on images holding greater-than-8-bit values are robust w.r.t. endianness

At least, we should check this (with the build farm) on a host with an endianness different than IA-32's or Intel 64's (e.g., a SPARC station). According to http://en.wikipedia.org/wiki/Endianness, * Intel IA-32 (and probably Intel 64 and AMD 64) are little-endian; * Motorola 68k, Sun SPARC and IBM System/370 processors are little- endian; * PowerPC, ARM, DEC Alpha, MIPS, HP PA-RISC and Intel IA-64 processors are bi-endian. -- Ticket URL: <https://trac.lrde.org/olena/ticket/124> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.
