[Feature-Request] {Add unit tests}

[Serafadam]

Start with the why:

Well, it's a general good practice.

Move to the what:

• depthai_bridge - Adding tests to verify Converters properly output messages based on some mock input DAI data.

• depthai_ros_driver - Adding several test cases to verify bare C++ code for PipelineGenerator to verify that parameters/objects are properly created.

Move to the how:

• depthai_bridge: For each converter add a test case with some example data. Verify that different options work.
• depthai_ros_driver: Test out pipeline generation based on different devices (mock device sensor list).

I guess best way to start is to start with one test case for each of those packages and add more later. cc @saching13

Yes. We can start with unit for each of the converters. Followed by integration tests where we run it on our devices with rpi, Jetson platforms.
