Support import/export as JSON résumé

[blacksd]

There's an open standard about handling the generic fields of a résumé in JSON. It would be nice to have the possibility to import and export directly using that format, and perhaps propose some schema improvements.

Thanks for creating this issue. Linking this with #12.

Agree that JSON resume is an awesome open standard. Import might be easy to add, but export might be difficult due to the OpenResume text fields being flexible while the schema is more fixed.

@xitanggg it would be nice to be able to version with git and branch different version of the résumé

@xitanggg TBH I'd be super happy with just having the import feature without having export available (to jsonresume)?
