LPY/refine improvments
The actual branch name is a bit deceiving, but this covers a few different additions/improvements which I'll list below:
- Length-Pitch-Yaw plots are now based on the first suspension channel to saturate, so the order of the saturation and lpy plugin have been flipped.
- Make a zoomed-in version of the refine plot to better see how well the refinement did. Tweaked index.cgi to put them side-by-side.
- Add a short description for the LPY plots in the webpage, since it was found to be confusing what was being plotted without an explanation.
- lpy.py: remove the flat y-lim axes warnings caused by flat timeseries. Now the y-limits are set manually in this specific case.
