Use lyluatex (if possible) to dynamically generate inline notation

[uliska]

When run with luatex it is possible to use the lyluatex package. I think it should easily be possible to use that for generating inline notation objects "on the fly" (with lyluatex's caching), which is of course much more elegant and flexible than having to add precompiled PDFs.

It has to be a certain template that is probably already present somewhere. I think it would be good to have options to print staff lines and clef, but have them off by default.

\lilyInline[clef=true]{ a'8 [ b' a' b' ] }
