Fixes #32

This it the same code as at Plots.jl, except it has: @optlevel 1

Here lower either is a bit faster (or no change) for startup, and shouldn't matter after. If in doubt I would use the other opt. level elsewhere, e.g. at VegaLite.jl.

FYI: I got startup of VegaLite.jl down to 1.9 sec. but that was with a setting you wouldn't want as first plot was slower, and second as slow.

What should be possible:

$ ~/julia-1.6-DEV-latest-7c980c6af5/bin/julia --startup-file=no -O0 --compile=min -q
