Fix the compile process

[MisshapenSmiley]

I ran into a few problems with the compile process, so here's how I've fixed them.

• gifsicle made a breaking change that stopped it being a CommonJS module, so I just selected an older version. Maybe a bandaid solution...
• Made the package list in DEVELOPMENT.md up to date
• Fixed nonexistent directory errors
  • When ./bin doesn't exist yet, don't try to remove it
  • ./bin/Levels doesn't seem to be a thing
• Also: Fixed typo in DEVELOPMENT.md, "sandalone" -> "standalone"

Why is it important to use the commonjs version?

(note to future self: otherwise this PR is good 👍 )

That's to fix the error I get when I take the latest version of gifsicle and run node compile.js:

PuzzleScript/compile.js:20
const gifsicle = require('gifsicle');
                 ^

Error [ERR_REQUIRE_ESM]: require() of ES Module PuzzleScript/node_modules/gifsicle/index.js from PuzzleScript/compile.js not supported.
Instead change the require of index.js in PuzzleScript/compile.js to a dynamic import() which is available in all CommonJS modules.
    at Object.<anonymous> (PuzzleScript/compile.js:20:18) {
  code: 'ERR_REQUIRE_ESM'
}

Oh gosh, yeah. I was having packages getting cached locally in a very stubborn way. Yeah, let's keep with the legacy module system for now :) Thanks for the reply!

Should I delete my branch? I've noticed that only the top point I listed above got committed yet.

Oh right huh, thanks for giving me a poke even though the issue was closed.

I've made the remaining changes by hand right now. Yes you can delete it if you wish :)

Cool! Now I'm able to compile without issues. Although, I must say, the typo now reads "stadalone" :)
