Adding OBD library to Arduino Library Manager.

[minyk]

Hi, @stanleyhuangyc It's really great if I can use ArduinoOBD library through Arduino's Library Manager. The manager checks library updates on IDE starting and manage the hard things. I found some article to do this:

• https://github.com/arduino/Arduino/wiki/Library-Manager-FAQ#how-can-i-add-my-library-to-library-manager
• https://www.arduino.cc/en/Hacking/LibraryTutorial

How do you think?
