Bumps [web-streams-polyfill](https://github.com/MattiasBuelens/web-streams-polyfill) from 3.2.1 to 4.3.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/MattiasBuelens/web-streams-polyfill/releases";>web-streams-polyfill's releases</a>.</em></p> <blockquote> <h2>v4.3.0</h2> <ul> <li>🚀 Optimize reading from a <code>ReadableStream</code> with buffered chunks. (<a href="https://redirect.github.com/MattiasBuelens/web-streams-polyfill/pull/170";>#170</a>) <ul> <li>When the stream has a chunk available in its internal queue, <code>defaultReader.read()</code> and <code>byobReader.read(view)</code> will now immediately return a resolved promise using <code>Promise.resolve()</code>. This turns out to be (slightly) faster than creating a <code>new Promise</code> and then immediately resolving it.</li> </ul> </li> <li>🚀 Optimize piping from a <code>ReadableStream</code> with buffered chunks. (<a href="https://redirect.github.com/MattiasBuelens/web-streams-polyfill/pull/170";>#170</a>) <ul> <li>When the stream has one or more chunks available in its internal queue, <code>pipeTo()</code> will now read all available chunks in a single batch and write them to the destination (while still respecting backpressure).</li> <li>These optimizations were <a href="https://github.com/nodejs/node/commit/199daab0b0822d6063a73b9362bfce8667d2a112";>inspired by Node.js</a>.</li> </ul> </li> </ul> <h2>v4.2.0</h2> <ul> <li>👓 Align with <a href="https://github.com/whatwg/streams/tree/080852ccd709e063cc6af239ae07fc040e365179/";>spec version <code>080852c</code></a> (<a href="https://redirect.github.com/MattiasBuelens/web-streams-polyfill/pull/161";>#161</a>)</li> </ul> <h2>v4.1.0</h2> <ul> <li>👓 Align with <a href="https://github.com/whatwg/streams/tree/fa4891a35ff05281ff8ed66f8ad447644ea7cec3/";>spec version <code>fa4891a</code></a> (<a href="https://redirect.github.com/MattiasBuelens/web-streams-polyfill/pull/156";>#156</a>) <ul> <li>Commit pull-into descriptors <em>after</em> filling them from the internal queue. This prevents an issue where an incorrect BYOB request would temporarily be visible through a patched <code>Object.prototype.then</code>, which broke some internal invariants.</li> <li>The <code>next()</code> and <code>return()</code> methods of <code>ReadableStream</code>'s async iterator are now correctly "chained", such that the promises returned by <em>either</em> of these methods are always resolved in the same order as those methods were called.</li> </ul> </li> <li>💅 Improve type of <code>WritableStreamDefaultController.signal</code>. (<a href="https://redirect.github.com/MattiasBuelens/web-streams-polyfill/pull/157";>#157</a>)</li> </ul> <h2>v4.0.0</h2> <ul> <li>💥 Rework the list of variants to have more modern defaults.
