Add two new, separate charts showing the avg10 and delta
total pressure over time for the CPU and IO resources. The height of
the avg10 data in each chart represents the percentage of time "some"
task was delayed over the specific resource during the last 10
seconds of the build. The height of the delta total data in each chart
represents the total time "some" task was delayed since the last sample
was collected. If the reduced_proc_pressure data is not present in the
buildstats log, then the new charts are not shown at all rather than
being present but unpopulated.
Note that the delta total graphs may appear "spikey",
oscillating from high values to low. This behaviour is fixed in a
subsequent commit.

The internal representation after parsing now matches exactly
what the drawing code needs, thus speeding up drawing a bit.
However, the main motivation is to store exactly that required
information in a more compact file.

This adds a new, separate chart showing the amount of disk space used
over time for each volume monitored during the build. The hight of the
graph entries represents the delta between current usage and minimal
usage during the build.
That's more useful than showing just the current usage, because then a
graph showing changes in the order of MBs in a volume that is several
GB large would be just flat.
The legend shows the maximum of those deltas, i.e. maximum amount of
space needed for the build. Minor caveat: sampling of disk space usage
starts a bit later than the initial task, so the displayed value may
be slightly lower than the actual amount of space needed because
sampling does not record the actual initial state.
