Cannot write GIFs to file.

Expected Behavior

Write GIF to file

Current Behavior

It crashes, for seemingly no reason.

Failure Information (for bugs)

I tried manipulating a PNG and writing it and it worked, but as soon as I tried any GIF, it crashes.

Steps to Reproduce

1. jimp.read() an image
2. modify it (optional)
3. write it to a file with a .gif extension

Code:

jimp.read(/* PATH TO IMAGE */, (err, img) => {
    if (err) throw err;
    img.write(`./gif.gif`)                
})

Context

• Jimp Version: v0.16.1
• Operating System: Windows 10 20H2 Build 19042.867
• Node version: v14.15.0

Any solution to this? My jimp implementation also reads and writes jpegs/pngs but gifs are not written.. the resulting file from uploading/writing a new gif is empty
