Invalid closing code

Looks like there is an error in Protocol. otherwise this errors is in implementations, js, java

A client who sends a 'close' message MUST set the reason field to a valid close code (as enumerated in Close Code Enumeration). 1001 SHALL be used for normal close cases.

From protocol MUST be sent 1001, but in both implementations is send 1000

Looks indeed like the clients are slightly wrong there, using 1000 instead of 1001 for pretty much everything. Not much of an issue but still a protocol violation.

When resolving this, an issue in the Java and Rust implementation should be filed (if needed).
