The Google Cast button is not shown for DASH streams

[vimto]

Current Behavior:

When using a DASH a src for the React Provider element and loading the player in Chrome, the Google Cast button is not shown.

Expected Behavior:

The Google Cast button should be shown for DASH streams.

Steps To Reproduce:

• Go to the Vidstack demo page: https://vidstack.io/player/demo/?framework=react&view=player&preset=dash in Chrome
• Select the Dash preset
• The Google Cast button won't be available

Anything Else?

The DASH streams we are using are supportd by Google Cast, which I've verified by testing with https://castjs.io.

It looks like the fix is simply including isDASHSrc in the canGoogleCastSrc check in the mime.ts file:

export function canGoogleCastSrc(src: Src): boolean {
  return isString(src.src) && (isAudioSrc(src) || isVideoSrc(src) || isHLSSrc(src));
}
