WpSpaJson APIs - Githubissues

introduced in 0.4.8, these types (SpaJson, SpaJsonBuilder, SpaJsonParser) haven't really been fleshed out or used yet.

[ ] implement manual methods that gir missed, basic constructors, etc
[ ] create an example use-case for them, whether that's an actual example or just a set of #[test]s
[ ] expose higher-level rust interfaces, etc
[ ] improve conversion to/from them via serde or something if possible?
[ ] consider also how they relate to libspa (though I think it entirely uses macros so isn't relevant or useful here?)
