* [Internal] Bridge between StreamInterface from PSR-7 and ReadableStreamInterface from ReactPHP
*
* This class is used in the server to stream the body of an incoming response
* from the client. This allows us to stream big amounts of data without having
* to buffer this data. Similarly, this used to stream the body of an outgoing
* request body to the client. The data will be sent directly to the client.
*
* Note that this is an internal class only and nothing you should usually care
* about. See the `StreamInterface` and `ReadableStreamInterface` for more
* details.
