- change output type from depth_array to gray16_array, which allows us to use this output format for any 16bit grayscale image, not just depth array.  Based on pull request feedback from Rahul.

- added a comment to clarify what dependencies are necessary and how to install them.

- Changed to allows use default time for wait_for_frames()
- Those above changes were verified in realsense_viewer.py in the realsenseutils project to make the 3 streams stable and reliable on the jetson nano

- added traceback in Vehicle.py to print any exception that terminates the vehicle loop, other than a keyboard interupt.

- added traceback in Vehicle.py to print any exception that terminates the vehicle loop, other than a keyboard interupt.

- added exception handler in Vehicle.py to print any exception that terminates the vehicle loop, other than a keyboard interupt.

- modified complete.py/manage.py to save depth and 'depth_array' type, so it can be handled specially in datastore.py
- modified datastore.py to handle 'depth_array' as a 16bit grayscale PNG image.

- give thread more time to quit.
- give camera more time to warm up.

- removed small 'i' from REALSENSE_D435i_IMU because it would not be copied with the lowercase letter in it, so I was getting an error about the config not existing.

RealSense-part added to the self test in realsense435i.py.  Added default config in cfg_complete.py.  Integrated into complete.py

Add documentation around OLED support

Add FPV web server

Add support for a PiOLED display to show useful information.

* Connect the PiOLED display over I2C, and configure the bus number.
* Change `myconfig.py` to update the bus number, and the display automatically shows useful information.
* Uses the `Adafruit_SSD1306` library.

Revert "Adding class WebFpv which is a simple web server which only serves the donkey car camera * Reduced the sleep time in the VideoAPI from 100ms to 10ms in order to achieve a less lagging web camera picture * Added the new WebFpv class with a very simple base_fpv html webserver file * Small pep-8 formatting updates in web.py and re-arranging the port variable to become a member in LocalWebController (makes more sense)"
