Improve plot

[sverhoeven]

Continuation of #30

• Plot vertical profiles
• Add axes
• Nicer axis extents/ticks
• Render all permutations of experiment
• Render more than one experiment
• Add legend
• Add color cycling
• Tooltip on hover
  • Simply use SVG title element. But only works if mouse is exactly over path.
  • Continuation in Add/improve hover effect on plots #82
• Styling/font similar to SolidUI/Charts
  • Tinkered with font family/size/weight/letter spacing etc now mostly similar
  • For now stick with fixed axes and no grid lines as in chart.js, but open for opions.
• Axis labels
• Make it possible to select variable Variable picker #84
• Make it possible to select time (playback controls?) Time slider for vertical profiles #85
• Reuse own component in favour of solidui/chart for timeseries as well
  • This makes the app much slower; can we optimize? Seems ok now
  • Reduce history interval to 10 minutes instead of 1 minute; somewhat better but still not great
  • Remove dead code / unneeded dependencies (chart.js, chart component)
  • Fix playwright test: if we stick with this, the canvas is gone, so we cannot screenshot it
• Make reactive (if data changes, update plot)
• Responsive width/height Make analysis items responsive #83
• Verify that gammaq/gammatheta always available
• Add skew-T/log-p plots Add skew-T log-p diagrams #75
• Move buttons to card header
• What should be the default height? (currently simply extending profiles by 400m)
• Do we want to modify units, e.g. from kg/kg to g/kg for more readable digits? Or time in hours/minuts rather than seconds?
• Make typecheck happy
