Example of how to use parameters/query args in edgedb-tokio

[nocduro]

Most of the examples on docs.rs and on github don't use parameters.

Would you consider adding a second example for query that includes using parameters? And maybe another one in the examples folder on github.

Or even just a link to: https://www.edgedb.com/docs/edgeql/parameters from the query docs

There is also another issue #172 that mentions confusion with the query args needing to be a tuple which might be helpful to put in the docs as well.

Thanks!

@nocduro Sure thing! I've also been putting together a repo with a number of examples (including parameters/arguments) that you can see here in the meantime: https://github.com/Dhghomon/edgedb_rust_client_examples
