The way in which the piping process behaves under various error
conditions can be customized with a number of passed options. It
returns a promise that fulfills when the piping process completes
successfully, or rejects if any errors were encountered.

Piping a stream will lock it for the duration of the pipe, preventing
any other consumer from acquiring a reader.

Errors and closures of the source and destination streams propagate
as follows:

An error in this source readable stream will abort destination,
unless preventAbort is truthy. The returned promise will be rejected
with the source's error, or with any error that occurs during
aborting the destination.

An error in destination will cancel this source readable stream,
unless preventCancel is truthy. The returned promise will be rejected
with the destination's error, or with any error that occurs during
canceling the source.

When this source readable stream closes, destination will be closed,
unless preventClose is truthy. The returned promise will be fulfilled
once this process completes, unless an error is encountered while
closing the destination, in which case it will be rejected with that
error.

If destination starts out closed or closing, this source readable
stream will be canceled, unless preventCancel is true. The returned
promise will be rejected with an error indicating piping to a closed
stream failed, or with any error that occurs during canceling the
source.

The signal option can be set to an AbortSignal to allow aborting an
ongoing pipe operation via the corresponding AbortController. In this
case, this source readable stream will be canceled, and destination
aborted, unless the respective options preventCancel or preventAbort
