Now the limits for template placemeent are given in cartesian coordinates.
For wire-type probes, it could be useful to have a radius:
e.g.
OPTION 1:
xlim: [20, 80]
xlim_coord: 'radial'
ylim: [-50, 50]
ylim_coord: 'cartesian'
zlim: [-50, 50]
zlim_coord: 'cartesian'
If radial then templates could be located in the cylinder between 20 and 80 um radius around the origin.
