Update use of Makie (v0.20.0) to avoid deprecations

[ConnectedSystems]

Makie v0.20.0 was released recently (see here)

This comes with a number of performance improvements and support for HiDPI screens, as well as a few deprecations.

I think we should be mostly okay, but one notable change is that resolution is now size:

# Instead of this:
tf = Figure(resolution=(1600, 600))

# Do this:
tf = Figure(size=(1600, 600))

FYI @Zapiano this means more seamless plotting between CairoMakie and other backends, especially on Mac (because of the improved HiDPI screen support).

WGLMakie gets some performance improvements too.

1. How do we "update" Makie's version since when it is only used inside an extension? Should we add Makie = 0.20.0 to the [compat] section of Project.toml?

2. Apparently one of the packages we depend on (DimensionalData) depends on version Makie's version 0.19.0. Is that an impediment, since Makie is only used by an extension..? I tried adding Makie = 0.20.0 to the [compat] section of Project.toml, going to my sandbox and updateing, but I got a compatibility restriction error:

Yes

Also yes. It means we can't update until this package also makes changes to update.
