Parses a URI into its component maps.

`return.parts` contains the parsed URI fields. `return.query` contains query parameters decoded with the same rules as `parse_query()`.

Example:

```uce
URI uri = parse_uri("https://example.test/docs/index.uce?q=uce#top");
String host = uri.parts["host"];
String path = uri.parts["path"];
String q = uri.query["q"];
```

Use `parse_uri()` when you need to inspect a full URL. Use `parse_query()` when you only have the query string.
