Description

New sketch for the OBOGS panel.

Closes #50

List any dependencies that are required for this change, including a full list of libraries required, especially if it is a new or otherwise unused library in the OpenHornet software.

[x] New software module (new software module for slave)
[ ] Bug fix (non-breaking change which fixes an issue)
[ ] New feature (non-breaking change which adds functionality)
[ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)
[ ] This change requires a documentation update outside of the automatically-generated Doxygen documentation.

[x] My code follows the style guidelines of this project
[x] I have complied with the software manual for this project
[x] I have performed a self-review of my own code
[x] I have commented my code fully with Doxygen compatible comments, particularly in hard-to-understand areas
[x] I have made corresponding changes to non-Doxygen generated documentation
[x] I have ran Doxygen locally, and it builds the docs successfully
[x] My changes generate no errors on compile in Arduino IDE
[x] My changes generate no new warnings on compile in Arduino IDE
[x] Any dependent changes have been merged and published in downstream modules
[x] (For sketches only) This sketch complies with OH-INTERCONNECT v10
[ ] If this sketch requires additional libraries, I have added it as a sub-module per the Arduino Libraries section of the Software Manual.

[ ] I have tested the sketch in-circuit in DCS with DCS-BIOS and outputs (displays, LEDs, etc.) function as expected.
[ ] I have tested the sketch in-circuit in DCS with DCS-BIOS and HID inputs (switches, pots, etc.) function as expected, with switches moving the correct direction.
[x] I have tested the sketch in-circuit in DCS with DCS-BIOS and any logic in the sketch has been tested and functions as expected.
[x] This code has not yet been tested in-circuit.
[ ] This code has not yet been tested in DCS-BIOS.

Installed the sketch. Without DCS running validated the switches send the expected DCSBios messages. With DCS Running.

Validated all the switches move in the correct direction.
I don't have the NUC switch installed in my pit. It's a simple 2 position switch and DCSBios setup. It should work fine, I would be surprised if it doesn't.
The OXY Flow knob works fine, and was tested multiple times and scenarios given the extra coding to get around the fact the interconnect diagram only has one pin on the knob hooked up. a. As a note added to the comments if the off position of the knob is connected to a pin, then the coding is a simple "rotary encoder" where there are 2 positions with -65535 and +65535 as the steps.
