Update tokio-tungstenite requirement from 0.18.0 to 0.19.0

[dependabot]

Updates the requirements on tokio-tungstenite to permit the latest version.

Changelog

Sourced from tokio-tungstenite's changelog.

0.19.0

• Allow users to enable/disable Nagle algorithm when using connect() helpers.
• Improve the behavior of the Sink for the WebSocketStream, so it does not return an error when it’s not necessary (when poll_flush() is called on a connection that has just been closed).
• Workaround an issue where rustls TLS backend expected domain in a certain format and reject IPv6 addresses if they contained square brackets in them.
• Update dependencies and remove unused errors.

0.18.0

• Update dependencies (underlying tungstenite core).

0.17.2

• Make Origin header case-sensitive (to keep compatibility with poorely-written servers that don't accept lowercase Origin header).
• Make semantics of the reading form the WebSocketStream more reasonable (return None instead of an error when the stream is normally closed).
• Imrpove the way poll_close() works by properly driving the close of the stream till completion.

0.17.1

• Update the tungstenite dependency (fixes a panic in tungstenite and MSRV), see tungstenite's changelog for more details.

0.17.0

• Update the dependencies, please refer to the tungstenite changelog for the actual changes.

0.16.1

• Fix feature selection problem when using TLS.

0.16.0

• Add a function to allow to specify the TLS connector when using connect() like logic.
• Add support for choosing the right root certificates for the TLS.
• Change the behavior of the connect() so that it fails when using TLS without TLS feature.
• Do not project with Unpin.
• Update the dependencies with important implications / improvements.

0.15.0

• Update the tungstenite-rs version to 0.14.0, check tungstenite-rs release for more details.

0.14.0

• Support for rustls as TLS backend.
  • The tls feature was renamed to native-tls and uses a OS-native TLS implementation.
  • A new native-tls-vendored feature that uses native-tls but forces to build a vendored version (mostly for openssl) instead of linking against the system installation.
  • New rustls-tls feature flag to enable TLS with rustls as backend.
  • stream::Stream was renamed to MaybeTlsStream and wraps a rustls TLS stream as well now.
