Intensity clipping when converting to webknossos.wkw format goes wrong

[arentkievits]

Datasets processed with exporter have weird histograms in WebKnossos. In the high intensity range, biological features are clipped, which should only be minimal. This is problematic.

Example of a weird histogram:

Example of a normal histogram:

the top dataset has a very high amount of artifacts, this definitely causes the clipping to go wrong, in order to preserve depth in the biology of the sample a higher lower bound for the percentile parameter in the import to render needs to be selected, eg 30-99 percentile clipping.
alternatively we can revise our import code to find and ignore such artifacts through some sort of masking.
the export code does not calculate the clipping, this is done on import.
