Migrate to bevy 0.14

[makspll]

Will fix #124

[makspll]

I am getting stack overflows on running codegen, which is strange, I would expect proper compilation failures

[makspll]

Oh it looks to be in the active feature computation stage which does make sense as the crate sets some features for bevy which might be out of date

[makspll]

There seems to be a dependency loop in bevy, or at least in the way the dependncies are processed

[makspll]

It seems to have been an issue in the way we computed dependencies, since dev dependencies were included and that lead to inifnite cycles between a crate and itself (bevy_math).

It seems we get compilation errors on bevy from new rust compiler features, so I do need to upgrade the codegen nightly version

[makspll]

This seems to be working now, examples are working fine

I'm positively giddy about this!

Got a chance to kick the tires and successfully updated my project to use the main branch and bevy 0.14. No issues on my end.
