Major rewrite of the WebSockets library:
- New: Moved library to an OO approach for WebSockets connections (Client/Server Classes)
- New: Abstracted underlying socket functionality (e.g. NI VISA TCP) for future secure WebSockets support
- New: Added TCP socket listener for listening for server socket connections
- New: Simplified API
- New: Added high-level Read function which internally handles fragmented and Ping frames
- New: Added WebSockets Client Example VI and modified examples to use new classes
- New: Added unit testing to source repository
- New: Added detailed documentation (.chm file) to LabVIEW Help menu and added examples to NI Example Finder
- New: Added palette support for LV2020
- Fix: Fixed incorrectly applied timeout values (timeout = approx. maximum time until VI returns)
- Fix: WebSocket-Client-Key is now correctly generated as a random string rather than being a constant

Note: A backwards compatibility layer is retained for legacy applications allowing upgrade with minimal application changes. It is strongly recommended to update applications to use the new library VIs.

- Fixed incorrect detection of multi-frame packets in Read.vi (thanks to ANDRÉ_CARVALHO)

- Added better support for Opcodes defined in RFC6455: Now supports reading/writing of PING/PONG frames and reading/writing of fragmented messages (opcode 0x0). Payload data will be returned for supported opcodes.
- Improved error handling of unsupported opcodes
- Replaced Opcode with Ring type-def
- Added 'Request URI' input to InitiateClientHandshake (defaults to '/') to improve compatibility with 3rd party WS servers
- Fixed timeout not being passed to subsequent TCP VIs in Read.vi

- Fixed an issue with incorrect EOL being used in InitiateClientHandshake.vi (better cross-platform support)
- Added support for sending additional headers in the client handshake / server response
- Added support for Sec-WebSocket-Protocol: The DoHandshake VI now has a 'supported protocols' input which allows (in order of preference) specification of supported protocols. If a supported protocol is found in the received header, it will be returned back to the client as per the WebSocket specification.

Note: The VI Package has changed name - please uninstall any previous versions of this package.
