divSpectrums ambiguous overload

[maulanaazhari]

failed to compile the code due to ambiguous function (similar to opencv function)

It builds on my machine (20.04) and under our Singularity (https://github.com/ctu-mrs/mrs_singularity/). However, this package is kinda old, and we are not planning on using it anymore. So it is not integrated into the MRS UAV System anymore. I have pushed a minor update that fixes the launch file and configs a little bit, so you should be able to run it if you really need it.

@cturmrsbot thanks for your quick response, I would definitely check out the Singularity!
