Bug fixes for parameters and keep-alive signal

[dee-gmiterko]

Hi,
I encountered two issues when using your library, namely:

• Fields incluced in _exclude list of API enpoint would be ignored altogether instead of using names without does as intended.
• Twitter API can occasionaly send empty line when there are no new tweets to be pulled and this fails on json parsing of recieved lines. Reference: https://developer.twitter.com/en/docs/twitter-api/tweets/filtered-stream/integrate/consuming-streaming-data > Responding to system messages > Keep-alive signals

"Fields included in _exclude would ignore list of API endpoint altogether instead of using names without does as intended."

Adding _exclude was a bad design -- I have to live with it till another major release. Which will be asap -- I guess. Thanks for pull requested!
