Address deprecated wasm-bindgen init api#13

This is the signature of the `__wbg_init` generated when using the latest version of wasm-bindgen. ```typescript /** * If `module_or_path` is {RequestInfo} or {URL}, makes a request and * for everything else, calls `WebAssembly.instantiate` directly. * * @param {{ module_or_path: InitInput | Promise<InitInput>, memory?: WebAssembly.Memory, thread_stack_size?: number }} module_or_path - Passing `InitInput` directly is deprecated. * @param {WebAssembly.Memory} memory - Deprecated. * * @returns {Promise<InitOutput>} */ export default function __wbg_init (module_or_path?: { module_or_path: InitInput | Promise<InitInput>, memory?: WebAssembly.Memory, thread_stack_size?: number } | InitInput | Promise<InitInput>, memory?: WebAssembly.Memory): Promise<InitOutput>; ``` We're currently using a deprecated api in our worker.js file. This causes the following warning to appear in the console when using the library  This PR fixes this issue by addressing the deprecated api
