This PR replaces TeeChart with ScottPlot for all plotting functionality.

Switching to an open source plotting library has been on the todo list for a long time (#70).

Recent experience has shown that TeeChart development is relatively unreliable (#122).

The main advantage of TeeChart over other solutions has always been the built-in editor and the legend checkboxes, which will have to be replaced using our own UI.

Major tasks:

  • Replace TeeChart.TChart chart object with ScottPlot.FormsPlot and adjust all relevant code accordingly
  • Add a UI for switching series on and off
  • Add a UI for editing the chart (minimum functionality: ability to edit axes limits and series styles)
  • Come up with a replacement for the TEN format (but keep import TEN functionality at least for a while)
