HDR with LUCID Triton Camera

[atar13]

NOTE: This issue is a subtask of #10. See that issue for an explanation of the issues we're facing with our current imaging system. This is one approach we should investigate to improve image quality.

I know several people were interested in looking into the imaging techniques. I am not that interested in CV, so I would like if I could just hand off what I have to someone else who is willing to learn about more advanced HDR stuff. In particular, it would be good to have this HDR code made to use the Triton camera.
I used some basic opencv code from online and ran an HDR algorithm on 4 1600x1200x3 8 bit images, taking 3.251 / 3 sec cpu time single core at 3GHz. Note that I expect this to run at least 10x faster on the Jetson with CUDA opencv build. So just a gut check, this does seem unreasonably slow right now. But also I don't know what I'm doing so it is probably easily optimized.
I found this page from our camera website which had some very nice examples of the types of things you can correct with hdr. Unfortunately, I think we are very quickly going to realize why Apple and Lucid are choosing to make custom hardware to do vision processing rather than pure software.
