Program should be able to download FFmpeg

[Adam-Kay]

Improvement Description

Most people do not know what FFmpeg is, nor want to figure out how to download it. Perhaps the program could install it for the user, and from then on it would be in PATH as suggested in #4 , and then doesn't have to be worried about again.

How to implement

Three stage option:

Preferred option

1. Attempt to install with winget - do "essentials" install if possible
   (Make sure to warn user about Microsoft Agreement that might pop up)

If preferred fails (WinGet is not available on device OR user declined agreement OR <other>)

2. 'Manual' install using https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-essentials.zip and PowerShell's Expand-Archive utility.

If all else fails

3. Search for ffmpeg.exe in current folder (#3)
   and if it doesn't exist, ask user for path to ffmpeg.exe (current behavior).

With the following now completed, a more lightweight FFmpeg Essentials package can be grabbed from WinGet instead:

• New package: Gyan.FFmpeg.Essentials version 6.1 microsoft/winget-pkgs#130561

• Can use where ffmpeg command for ffmpeg install detection (also searches in current folder, conveniently resolving Program should detect FFmpeg if it's in the same folder #3)
• Can use command from here to add path for secondary install option (and in theory remove, but unlikely to be needed).

Just thought that I can also use where winget to see if the machine has winget installed. If not, it can skip directly over to secondary
