used serial_number to identify and set type to a specific device (#663)

3rd party joycons (tested on joysky "wireless controller for N/SW) reported the same name "wireless gamepad" so i was unable to correcly address the left/right type of joycon. 

By using bluetooth serial number as additional identifier we can target specific device with correct type.

Changes:
- used serial_number as additional condition in "check list of custom controllers specified" block
- SController now incapsulate serial_number and use it for hash, equals, serialize etc
- Read the 5 index of 3rdPartyController file on _3rdPartyControllers
