Unable to use `skia_canvas@0.5.4` on deno main

[rgbkrk]

At least as of https://github.com/denoland/deno/commit/be7e2bd8c1883c6bf58db8ff40954ed7ee53b5c5 (and earlier), I can't import and use skia_canvas.

Example code in ffi_bug.ts:

import { createCanvas } from "https://deno.land/x/skia_canvas@0.5.4/mod.ts";

const canvas = createCanvas(800, 250);

Running it:

Looks like the op -> op2 for ffi work needs to handle more buffer types (https://github.com/denoland/deno/pull/20509).

Closing as the issue is in Deno main and is being worked on.
