Reading and setting node parameters, setting expressions and keyframes.
Different parameter types are modeled with a Parameter enum, to get to a concrete type, use pattern matching:
use hapi_rs::session::new_in_process;
use hapi_rs::parameter::*;
let session = new_in_process(None).unwrap();
let lib = session.load_asset_file("otls/hapi_parms.hda").unwrap();
let node = lib.try_create_first().unwrap();
if let Parameter::String(p) = node.parameter("single_string").unwrap() {
assert_eq!(p.get_value().unwrap(), &["hello"]);
assert!(p.set_value(&["world".to_string()]).is_ok());
