Remove lodash as a dependency

[connor-baer]

Purpose

Lodash is one of Circuit UI's larger dependencies. It doesn't support treeshaking out of the box¹ and is included in some of the basic building blocks of Circuit UI, so most components bear its performance cost.

Since we will drop support for legacy browsers in Circuit UI v5, we're now able to replace Lodash with native browser APIs and a small set of utility functions.

Approach and changes

• Replace Lodash with native browser APIs and a small set of utility functions

Definition of done

• Development completed
• Reviewers assigned
• Unit and integration tests
• Meets minimum browser support
• Meets accessibility requirements

Footnotes

1. Requires the use of babel-plugin-lodash. ↩

Amazing! Thanks a lot for tackling this 🪶 Nice to see that we already had most of the helper functions we needed, too! Just left a few thoughts

That's because I've been working towards this for a while, even before #1504 and #1505 😏

[connor-baer]

Whoops, I thought auto-merge would wait for your review. Sorry, @robinmetral!

[robinmetral]

😄 no worries, this looks great! 🎉
