chore: apply more eslint rules

[SethFalco]

Updates our ESLint rules to make the code easier to read and maintain. I've been looking at some of the math heavy functions, and especially with so many instances of comma separated variable initializations rather than one variable per line, it's quite the slog to go through.

• Prefer declaring/initializing variables one at a time, rather than comma separated.
• Blocks like if, for, while etc should always use curly braces, even if it's a single line.
• Move @typedef below import strings.
• Update prettier to the latest version.
• Replaces special characters in descriptions with normal double quotes (") or apostrophes (').
• Imports are sorted in alphabetical order, applied automatic fixes but but not persisted in config.
• Variables should prefer let or const, applied automatic fixes but not persisted in config.
