Replaces placeholder tokens in a URI template with the corresponding tile properties.

The URI template should contain the tokens:
- `{level}` for the tile's subdivision level.
- `{x}` for the tile's x-coordinate.
- `{y}` for the tile's y-coordinate.
- `{z}` for the tile's z-coordinate.

@param {Object} tile - The tile object containing properties __level, __x, __y, and __z.
@param {string} uri - The URI template string with placeholders.
@returns {string} The URI with placeholders replaced by the tile's properties.
