Type annotations on encode() returns Buffer in browser instead of Uint8Array

[ekzhang]

Hi there! Thanks for this wonderful library. Just wanted to report what appears to be an inaccuracy in the type annotation for encode():

cbor-x/index.d.ts

Lines 61 to 63 in f531383

	export function encode(value: any): Buffer
	export function encodeAsIterable(value: any): Iterable<Buffer | Blob | AsyncIterable<Buffer>>
	export function encodeAsAsyncIterable(value: any): AsyncIterable<Buffer>

It returns a Buffer, but when I call encode() in a browser, I get a Uint8Array instead:

This means that when you use it in TypeScript, I get an error when trying to type it as Uint8Array:

Type casting as workaround seems to resolve compile time issue:

// Note: The types for cbor-x are incorrect here, as encode() actually
// returns a Uint8Array in the browser. Cast to fix the type error.
const data = <Uint8Array>(encode(message) as unknown);
