raise connection error before close on bad frames

[lenkan]

When the socket receives a bad frame during a read, it should raise a connection error by sending a connection.close frame and wait for the connection.close-ok before closing the socket.

See https://www.rabbitmq.com/protocol.html

Currently, the tcp connection is closed immediately on EOF or a bad frame in

deno-amqp/src/amqp_socket.ts

Line 317 in 6948c4d

this.close();
