[sane-devel] new backend

[Frank Zago]

another useless backend:

This new backend supports the Relisys Scorpio/Taurus/Infinity VM3552. It
should also support (with little changes) the VM4552 and the VM6552.
This scanner has also been rebadged as: Piotech Splendeur 3024, Plustek
OpticPro 2400SP, and Trust Imagery 4800 SP+. The Trust Imagery 2400SP and
9600SP are likely to be a derivative too.
