Add examples for histogram functionality

[PaulaScharf]

Thank you for providing this repository!
Im not sure, but I think the two examples in this repo are almost the same as the ones given for the vl53l8cx library.
It would be nice to have usage examples for functions like "cnh_init_config", "cnh_create_agg_map" or "cnh_calc_min_max_distance".

Or perhaps you could direct me to some sources, where I can find out more about the usage of the histogram functionalities.

Hello @PaulaScharf ,
unfortunately, I do not have band to work on it. Anyway, you can download the "STSW-IMG043_ULD" package from this link. Take into account that all the APIs of the ULD are wrapped in the Arduino class. You can inspire on the "Example_12_cnh_data.c" application to implement an example using the cnh APIs also in the Arduino environment. It would be great if you can help to add this example into the Arduino library. Any contribution will be appreciated.
Best Regards,
Carlo
