CompressionOptions class

Options controlling compression in a WebSocket.

A CompressionOptions instance can be passed to WebSocket.connect, or used in other similar places where WebSocket compression is configured.

In most cases the default compressionDefault is sufficient, but in some situations, it might be desirable to use different compression parameters, for example to preserve memory on small devices.
