[module] read in and decode stereo camera messages

[kirkscheper]

Added a module to read in and decode messages from a stereo camera using a UART connection. Module is in sw/airborne/modules/sensors.

Please let me know if I need to move, change update anything.

Idea... I can also make the baud rate configurable in the airframe file. Might be useful considering the issues with the previous attempt to push to master.

[gautierhattenberger]

that is indeed a good idea to be able to set both port and baudrate

Would also make sense to not "hardcode" SEND_STEREO to true in the makefile...
Better define it to TRUE by default in the .c file and check it with #if SEND_STEREO
Or even better make it a flag that you can change at runtime...

Also please add the configure and define options to the documentation section in the module xml.

And probably most importantly: what kind of "stereocam" is this module for??

[kirkscheper]

The stereocam here is a custom design by Christophe de Wagter that is extensively used at the TU Delft. We have a couple of people working on this camera now in paparazzi, that's why I am trying to push this module now.

Thx!
Would be really nice if you could document the configure and define options with their respective xml tags in the module xml.
That way they are properly used in the generated documentation.... (see e.g. the digital cam module):

path incorrect...
