(IMPORTANT: It turns out that this version has a serious issue in CJS build. Please use v3.4.1 instead.)

This release is mainly to change build tooling and package file structure. It now uses esbuild to build esm bundles. The esm bundles are in esm folder, and default cjs bundles are in the root folder.

• [BREAKING CHANGE] index.cjs.js is renamed to index.js (explicit cjs usage is no longer documented in readme)
• [BREAKING CHANGE] index.iife.js is removed (never documented and not configured properly)

Changes:

• #350
• #348
• #343
