Bump SDK constraints for pub (#67)

Use a 2.12.0 lower bound since pub does not understand allowed
experiments for earlier versions.

Use a 3.0.0 upper bound to avoid a warning in pub and to give some
flexibility in publishing for stable.

This package exposes the StreamChannel interface, which represents a two-way communication channel. Each StreamChannel exposes a Stream for receiving data and a StreamSink for sending it.

StreamChannel helps abstract communication logic away from the underlying protocol. For example, the test package re-uses its test suite communication protocol for both WebSocket connections to browser suites and Isolate connections to VM tests.

This package also contains utilities for dealing with StreamChannels and with two-way communications in general. For documentation of these utilities, see the API docs.
