fix: cross disk relative paths

[mvanbutselaar]

This PR contains a:

• bugfix
• new feature
• code refactor
• test update
• typo fix
• metadata update

Motivation / Use-Case

We use Karma and Webpack, as the base for a testing tool, which can be installed globally. On Windows there is an issue when the tool is installed on one drive (C:), and the codebase being tested is on another drive (F:).

The issue is with relative path resolving on two absolute paths on different roots/drives, which returns an absolute path. This causes the process to get stuck infinitely after compilation, due to not being able to read the output (because the lookup key is not relative).

Hey, is this something you are still interested in?

[mvanbutselaar]

Yes we are still interested in this. I just rebased on latest master, what else can we do to move this forward?

[codymikol]

He @mvanbutselaar , sorry for the delay. We just released a v5.0.0 release that changed quite a bit since this PR. If you're still interested, would you mind seeing if this is still an issue against the latest release?

We no longer use relative paths from what I cant tell so hopefully this is resolved for you 🤞 .

If not I can do my best to help you get this resolved in the latest version.

Thanks for your contribution, it is much appreciated!

By the way, paths are still broken for Windows with the current master build:
Error: EINVAL: invalid argument, mkdir 'C:\Users\Simon\AppData\Local\Temp\_karma_webpack_82360\D:\code\osmd\opensheetmusicdisplay\dist\src'

Maybe something like this PR is still needed.

(On MacOS, the path issues seem solved with the current master)
