Spice up the README. Wanted to add a pic of my Sonix but wouldn't help

There are 3 kinds of device-specific folders :
addons/ contains actual usb chip support code for each device.
sensors/ contains code to handle CMOS sensors, as each model
of a specific brand usually have a different CMOS chip
despite a common usb chip.
cstransforms/ for colorspace transforms so other device using
the same weird colorspace can reuse the code (not yet
used, sonix has its own code for now). It should be
possible to use Translator-based transforms, making
it easy to support webcams sending JPEG pictures.
Another option is to turn all cstransforms into actual
Translators usable by other apps, or also media codecs
but that would be more work for few added value.
