Implement imgui.MultiPlotLines into ImGui wrapper and expose to plugins

[ESV-Sweetplum]

Is your feature request related to a problem? Please describe.

ImGui's plotting capabilities are currently extremely limited, and there's a reason so many plotting libraries exist for Dear ImGui (such as ImPlot).

Describe the solution you'd like

Implement multiPlotLines into plugins to allow for multiple lines on on eplot.

Describe alternatives you've considered

I've thought about ImPlot, but I chose multiPlotLines in particular because it should be easy to integrate into the existing ImGui wrapper. We could also create multiple windows for each plot, but that hurts both the visualization capabilities of a plot, as well as cleanliness of the editor.
