merge together camCalib, dualCamCalib, camCalibWithPose

[traversaro]

This issue is part of #193 .

[Nicogene]

We should also consider to include in this refactoring also camCalibWithPose

[drdanz]

just for reference, camCalibWithPose is an ugly hack and should be re-architectured

Beauty is in the eye of the beholder @drdanz :-)

I ~~wrote it~~ took the camCalib and added stuff inside in order to avoid an extra module, therefore I'm allowed to be disgusted!

Actually I wasn't alone though but I'll take the blame!

[alecive]

Well that changes things a bit :-) I was already picturing a poor phd student crying in a corner because you didn't like his code 🤣

This won't happen any time in the future.
