add file match to find font()

[cormullion]

Since on Slack I wondered to @jkrumbiegel why this wasn't currently possible, I thought I'd better make an effort and try adding it myself... :)

The intention is to allow specifying a font by giving a filename. So eg in Makie you can now go:

f = Figure()
...
f.scene.attributes[:font] = "BenguiatGothicStd-MediumObl.otf"

This doesn't really add very much functionality since Julius' existing font finding stuff is already pretty good, but users might expect that this more basic way of specifying a font would also be possible.

I also moved the docstring to the exported findfont() function, not sure whether its more likely to be read there.

Thank you! I've added something similar to AbstractPlotting yesterday https://github.com/JuliaPlots/AbstractPlotting.jl/pull/611, so I'm not sure if it makes sense to add this in FreeTypeAbstraction as well. Or if it would have made more sense to add it here in the first place. What do you think @SimonDanisch?

Haha - happy to go with your version, I'm sure it's better!

[SimonDanisch]

Well, now that you say that... FreeTypeAbstraction seems like the right place, since more packages will profit from a more consistent font loading experience^^
