fix: lazy load GifUtil rather than nextTick

[SimenB]

Inspired by the lazy helper in babel: https://github.com/babel/babel/blob/e498bee10f0123bb208baa228ce6417542a2c3c4/packages/babel-plugin-transform-modules-commonjs/src/index.js#L200-L207

The process.nextTick approach prints warnings when using Jest.

ReferenceError: You are trying to `import` a file after the Jest environment has been torn down.

      at node_modules/gifwrap/src/gifcodec.js:7:15

The real solution here is to split up the files to avoid any dependency cycles, but this works as well without being async

Any chance this can get in?

edit:
I applied this change with the help of
https://www.npmjs.com/package/patch-package
instead of forking and it works well.
Thank you @SimenB

@jtlapp this would save a lot of people from headache when writing tests. Please merge and publish.

If you need any help doing so, let us know. Happy to help and give insights why this fix would be beneficial :)

[jtlapp]

Okay done. I haven't verified the push, but I'll jump in if people report problems.

[jtlapp]

All tests pass. Published to NPM.
