Font package review

Hi all,

Recently, at the request of my youngest child, who is in his high
school marching band [1], I took over as maintainer of the mscore
package (MuseScore). I'm working on unbundling some stuff from it.
One of them is a music font:

I have never attempted to package a font before. I would really
appreciate it if those of you who are familiar with packaging fonts
for Fedora could take a look and tell me what I've done wrong [2].


[1] How did I get old enough to have my youngest be in high school?
There's something wrong there, because I am certain that I turned 20
just a year or two ago.
[2] I've never done this before, so I'm sure I did *something* wrong,
and probably multiple somethings.
