Set up criterion and impl std::error::Error for error types

[friendlymatthew]

This commit moves to criterion for its benchmarking suite. Also impls std::error::Error for jiter errors. Right now it fails to do:

use jiter::JsonValue;

// from the examples
fn main() -> Result<(), Box<dyn std::error::Error>> {
  let json_data = r#"
      {
          "name": "John Doe",
          "age": 43,
          "phones": [
              "+44 1234567",
              "+44 2345678"
          ]
      }"#;
  let json_value = JsonValue::parse(json_data.as_bytes(), true)?; // <- can't do this right now.
  println!("{:#?}", json_value);

  Ok(())
}
