Log piezo positions for each trigger

[vigji]

It was happening in the previous software, now it looks like there's only amplitude of piezo oscillation. It would be good to have exact piezo position at the onset of each plane trigger.

I do not understand what you mean Luigi. Can you expand this please?

Having a list of n elements where n is the number of saved planes, with the piezo position at the time of each image trigger

[diegoasua]

There is already in metadata piezo_max,piezo_min and voxel size together with n_planes and n_skip_start. You can figure out where each plane starts from that knowing that the first plane is triggered at piezo_min.

For convinience, piezo log is calculated and added to metadata in PR #45
