impl std::error::Error for Error

[stijnfrishert]

Hey there!

First of all, want to say I'm glad I found a rust library that does SF2! Well done :)

Is it possible that the error type implements std::error::Error? This makes interaction with other libraries way easier. I recommend using thiserror and I'd be willing to implement this and do a pull request?

Also, are you going to split off soundfont-rs into its own repo?

Hey! I'm very aware of the Error situation right now, I just did not have enough motivation lately to define all possible errors that OxiSynth can throw, and () was used as a placeholder (in some places &str was used, which is obviously a terrible idea) And yes, I also want to use thiserror, it seems to be the best solution for a project of this scope.

Also, are you going to split off soundfont-rs into its own repo? For now, I don't see a reason to do so, as OxiSynth is probably the only consumer of it. But sure I'm open to split it anytime, if there is a need to. It was meant to be completely standalone anyways.

And thank you for your interest, I'm open to any suggestions.
