Missing binding to `Blob.prototype.bytes`

[nasso]

Spec: https://w3c.github.io/FileAPI/#ref-for-dom-blob-bytes

wasm-bindgen/crates/web-sys/webidls/enabled/Blob.webidl

Lines 32 to 36 in c35cc93

	// read from the Blob.
	[NewObject] ReadableStream stream();
	[NewObject] Promise<DOMString> text();
	[NewObject] Promise<ArrayBuffer> arrayBuffer();
	};

This would be nice to have, as it allows directly going from Blob to Uint8Array, skipping the ArrayBuffer step.

If it's just a matter of updating the Web IDL and nobody has anything against it, I'd be down to open a PR!
