feat: remove Buffer support and bundle polyfill (#2526)

- Removes need for bundlers to polyfill the `Buffer` class. `UInt8Array` are used instead which are native to the browser and node.
- Reduces bundle size 7.1kb gzipped and eliminates 4 runtime dependencies: `base-x`, `base64-js`, `buffer`, and `ieee754`.

BREAKING CHANGE: All methods that previously took a `Buffer` now accept a `UInt8Array`.
