v0.15.0

What's Changed

• Update web_socket_channel, min Dart SDK is now 3.3 #91
• Support headers emulation in web context - so it's possible to pass custom connection headers to the backend when using Centrifugo v6 and connect proxy. Also added setHeaders method to update headers #92.

This release changes headers in ClientConfig from Map<String, dynamic> to Map<String, String>. This is a breaking change, but it must not cause huge troubles beyond a simple refactoring.

Usages of dart.html were removed in this release. Also some internal optimizations were done to allocate less when constructing Protobuf command data.
