Migrate API to support XQuery 3.1

+1 ;)

I notice that mongodb:insert supports maps for the $documents parameter, but mongodb:find returns strings rather than maps. This is fine, as we can just use parse-json to handle the results, but now that XQuery 3.1 supports maps and arrays and now that eXist has native support for parse-json (allowing us to drop dependencies on xqjson), I think there are still definitely opportunities to migrate the API to support these nice and convenient features of XQuery 3.1.

Similarly, are you considering bringing the module into line with the EXPath "mongo" spec? I see the function signatures already are map-centric, rather than string-centric, e.g., http://expath.org/spec/mongo#fn.insert, http://expath.org/spec/mongo#fn.find.

If so, I'd be happy to help update the tests, docs, etc. here. Let me know if I can be of assistance.

thnx @joewiz , yes the intention is to make the extension in line with the spec (my name is on it as well). I had a huge backlog, which is almost done. I'll upload a new version soon...
