build(deps): bump web-streams-polyfill from 4.2.0 to 4.3.0

[dependabot]

Bumps web-streams-polyfill from 4.2.0 to 4.3.0.

Release notes

Sourced from web-streams-polyfill's releases.

v4.3.0

• 🚀 Optimize reading from a ReadableStream with buffered chunks. (#170)
  • When the stream has a chunk available in its internal queue, defaultReader.read() and byobReader.read(view) will now immediately return a resolved promise using Promise.resolve(). This turns out to be (slightly) faster than creating a new Promise and then immediately resolving it.
• 🚀 Optimize piping from a ReadableStream with buffered chunks. (#170)
  • When the stream has one or more chunks available in its internal queue, pipeTo() will now read all available chunks in a single batch and write them to the destination (while still respecting backpressure).
  • These optimizations were inspired by Node.js.
