fix!: Set max listeners to tolerate backpressure

If a file isn't immediately put into flowing mode, then backpressure
could be invoked right away. Doing so can add many more event listeners
onto the stream as it uses the async iterator. This increases the max
listeners above the default for a little more tolerance before seeing
the nasty node warnings about event emitter leaks.

BREAKING CHANGE: `node 16` is becoming unsupported soon. Change the
supported versions to be >= `18`

Fixes: #41
