Replace TOML parser to support dotted keys in wrangler.toml

[leaysgur]

Hi. 👋🏻

It seems toml module does not support some TOML features like dotted keys.

BinaryMuse/toml-node#51

For example,

[build]
upload.format = "service-worker"
command = "npm run build"

This ends up with Unable to parse wrangler.toml: SyntaxError: Expected "=", [ \t] or [A-Za-z0-9_\-] but "." found. error now. (Of course this is valid TOML for wrangler CLI.)

And also toml module is not actively maintained, so why not use another implementation? 👀

Hello! 👋 This looks great, thanks for the PR! 😃 Seems like this package is more popular than toml too. 😅

Version 1.3.0 has just been released, including this change. 🎉 Let me know if you have any problems with it. 🙂
