## Description
Makes `Ident` consistent with vanilla by prepending the default
namespace if none is provided in the constructor.
Previously, the constructor did not normalize `foo` to `minecraft:foo`.
This could lead to subtle bugs when the ident is eventually unwrapped
with `Ident::as_str`. (comparing `foo` with `minecraft:foo` while inside
the `Ident` was still handled correctly).
## Test Plan
Steps:
1. `cargo test`
This is my first time contributing here so I was pretty unfamiliar with
the codebase and may have done some things incorrectly.
## Description
- Added a sound extractor to extract sound event ids and identifiers
- Added a `Sound` enum (with a build script) to represent sound effects
- Added a `play_sound` method to `Instance` and `Client`
- Re-implemented sound effects in the parkour example
## Test Plan
I tested this using the sounds I added to the parkour example.
