This PR adds a 'Peaks on Probe' widget that plots the peak locations overlaid on a plot of the probe (I am not a huge fan of the name myself, feel free to suggest others!). This PR closes #2986.

This plot has come up a few times in documentation and tutorials so I think could be a handy plotting function to have. A nice future addition would be to color-by-unit but if understand correctly from @samuelgarcia this is not currently possible as peaks do not hold unit. For me it is okay to include as-is and refine later if desired, the main reason I would like it is to import and call it from the motion/drift tutorial in #2879.

Overview

The function works by taking two main inputs, pre-calculated 'peaks' and corresponding 'peak_locations'. This can be either a single one of each or a list of corresponding entries. If multiple peaks / peak locations are passed, they are plot on different column axes of the same plot.

It is optional to select to only plot peaks from a certain segment, or between two times, to restrict the y-axis limits and to handle how peaks are decimated before plotting.

Questions

I think I might be using make_mpl_figure() wrong, I am performing 1 index operation to move the Axes objects to a 1d array here. Is this okay?
