v2.0.0-pre1

Release notes:

- Overhaul: sync (requires `node` > 19), ESM-only.

v2.0.0

Release notes:

- No functionality changes.
- To run in `node`, `random-uint-below.js` now requires `node` 19.
  - If you cannot upgrade to `node` 19, you can pass the `--experimental-global-webcrypto` flag to older versions of `node` as a workaround.
  - All major browser remain well compatible.
  - `deno` and `bun` remain compatible.
- Builds are only available as ESM (JavaScript modules), using ES2020-compatible syntax.
