App does not work with glyphs using quadratic curves

[rimas-kudelis]

I'm trying to run the MFEKglif 2.0.1-revision-1 flatpak and when trying to open a glyph with quadratic curves, the application exists with the following error:

panicked at /run/build/MFEKglif/cargo/vendor/glifparser/src/outline/create.rs:137:17:
internal error: entered unreachable code: Quadratic point in cubic glyph! File is corrupt.

For what it's worth, I don't believe the file is corrupt, it just uses quadratic curves. Here's an example file: a.zip.

I happened across this issue while checking on this repo by chance and I do believe the current handling of quadratic curves seems to be incorrect. I'm a bit in over my head on this but this is at minimum a bug in https://github.com/mfek/glifparser.rlib but possibly there's some odd behavior in this program directly as well. Thank you for the report! I did verify using fontforge's viewer that the file is entirely valid.
