Picks up the upstream fix (sitespeedio/compare#171) for filmstrip
404s in the compare view. The previous bundle constructed frame URLs
on a fixed 100 ms cadence inside (FVC, LVC), which broke on any run
where visual progress went flat between two boundaries — the
expected JPGs were never written, so the strip showed broken cells.

The upstream pass now reads the frame timestamps straight from
_visualMetrics.VisualProgress (one JPG per VP sample, named after
that exact ms), and lets the existing 100 ms padding step
forward-fill the uniform grid so the rendered strip still reads
"nothing happened for 2 s" differently from "everything changed
in 50 ms".
