max_allowed_packet issue when using ## for binlogEvent in stream

#### error message like below:
```
log event entry exceeded max_allowed_packet; Increase max_allowed_packet on master
```
#### the stack is:
``` python
for binlog_event in stream:
File "/usr/lib/python2.7/dist-packages/pymysqlreplication/binlogstream.py", line 408, in fetchone
pkt = self._stream_connection._read_packet()
File "/usr/local/lib/python2.7/site-packages/PyMySQL-0.7.11-py2.7.egg/pymysql/connections.py", line 1014, in _read_packet
packet.check_error()
File "/usr/local/lib/python2.7/site-packages/PyMySQL-0.7.11-py2.7.egg/pymysql/connections.py", line 393, in check_error

raise errorclass(errno, errval)
InternalError: (1236, u"log event entry exceeded max_allowed_packet; Increase max_allowed_packet on master;
```
#### I checked master's max_allowed_packet setting, and i found it was setting to 1GB, so i adding the setting on my code, here's the detail:
``` python
conn_setting = {'host': HOST, 'port': 3306, 'user': USER, 'passwd': PASSWORD, 'charset': 'utf8', 'max_allowed_packet':1*1024*1024*1024}
binlog2sql = Binlog2sql(connection_settings=conn_setting, start_file=FILE, start_pos=POS,
end_file="", end_pos="", start_time="",
stop_time="", only_schemas="", only_tables="",
no_pk=False, flashback=False, stop_never=False,
back_interval=1.0, only_dml=False, sql_type=['INSERT', 'UPDATE', 'DELETE'])
```

#### but it seems like having no effect. please check this out.
