Apple Silicon build

[sindresorhus]

Would be nice useful if this package included an Apple Silicon build of FFMPEG.

There is a fork here with a signed darwin-arm64 ffmpeg binary provided: https://github.com/cypress-io/node-ffmpeg-installer

@flotwig, could your fork PR those changes into this repo? evermeet.cx won't support darwin-arm64 in the foreseeable future, so it would be nice to find an alternative.

I'm trying to understand the changes introduced in your fork and it seems pretty basic but I can't make sense of where the binaries are coming from, would you mind helping me out?

[flotwig]

@raulrpearson the binary comes from installing this branch: https://github.com/cypress-io/node-ffmpeg-installer/tree/darwin-arm64 which is an optionalDependency in the master package.json

Got you, @flotwig, thanks for clarifying. I didn't know dependencies could be specified like that.
