GOR listener failure

[r4um]

Exact start of panic

panic: runtime error: send on closed channel

goroutine 4 [running]:
gor/listener.(*RAWTCPListener).processTCPPacket(0xc20009b410, 0xc208eb5cc0)

I reproduced this bug, and most likely it caused by "ulimit -n" settings. At least in my case. Try to increase it: ulimit -n 64000, ensure that limits applied to gor process: cat /proc/$pid/limits

Also latest release https://github.com/buger/gor/releases will not crash on panic, it just log it in file.
