Ffmpeg.wasm not working in Chrome extension due to SharedArrayBuffer

**Describe the bug**
I can't seem to be able to use ffmpeg.wasm in a chrome extension anymore.

**To Reproduce**
I simply used the example from https://github.com/ffmpegwasm/chrome-extension-app and loaded it into
my chrome as an extension, this now throws an `Uncaught (in promise) ReferenceError: SharedArrayBuffer is not defined` error.
I've also attempted to run ffmpeg.wasm from the sanbox environment of a chrome extension, but it resulted in the
same error.

**Expected behavior**
A working example of ffmpeg.wasm running inside of a chrome extension (preferably locally hosted).
