feat(ffmpeg): Update version to 4.3.1

[eliotik]

Updated ffmpeg binaries for:

• darwin, linux platforms
• windows platform skipped

[eliotik]

Hi @kribblo , can you please merge it and then do platform/* npm run upload?
I cannot upload new version of ffmpeg binaries to npm registry since I'm not owner of these optional repositories.

Looks like there's a fork that is more up to date 🤔
https://github.com/devdanim/dnm-node-ffmpeg-installer

[whyboris]

There's also this: https://github.com/SavageCore/node-ffprobe-installer 🤔 unsure if it's a good alternative

Yo what's the hold on this @kribblo

[kribblo]

Hey sorry, because of reasons maybe more people should maintain or take over this, started a discussion about it and will be happy to invite help: #52

[deevus]

@eliotik Are you able to update these to 4.3.2 and squash?

[deevus]

For Windows builds, can we use https://github.com/GyanD/codexffmpeg

[deevus]

Or https://github.com/BtbN/FFmpeg-Builds

@whyboris @eliotik Any thoughts on #53?
