I've found a crate that handles both comments and trailing commas in
JSON. It is a fork of `serde_json`, but it is maintained & up-to-date.
Sadly RawValue seems to not play nicely with it; I've ran into
deserialisation issues around use of RawValue. For this PR I've migrated
to `Value` API.
Obviously this is just a point of discussion, not something I'd merge
straight away. There may be better solutions to this particular problem.
I've also noticed that `serde_json_lenient` does not handle trailing
commas after bindings array. I'm not sure how big of an issue that is.
Release Notes:
- Improved handling of trailing commas in settings files.
