add interactive zoom inset

[SimonDanisch]

using GLMakie

fig = Figure()
ax = Axis(fig[1, 1], title="Interactive Zoom Inset Demo")

# Create some data
x = 1:100
y = sin.(x .* 0.1) .+ 0.5 .* cos.(x .* 0.3)
lines!(ax, x, y)

# Create an interactive zoom inset
# The rectangle defines the initial zoom region: Rect2f(x_origin, y_origin, width, height)
zi = zoom_inset!(ax, Rect2f(30, -0.5, 20, 1.5))

These results are subject to substantial noise because GitHub's CI runs on shared machines that are not ideally suited for benchmarking.

Changes made:

• inset axis now works with transformations (both transform functions and model transforms)
  • The inset axis also works with a different transform_func (xscale, yscale) than the parent Axis. So you can have a linear view into a log plot/axis. (This requires no model transformations. Bottom right in refimg does this with xscale = log10 in the parent axis.)
• placement of the inset axis now dodges the zoom rect by default
• the dotted lines now connect corresponding corners. These lines are picked to never overlap with either the zoom rect or the inset
• added refimg test:
