Title: Added separate WIRE define for Teensy boards

Teensy boards use the same Wire API as Arduino, but newer Teensy boards don't use the AVR microcontroller (and therefore do not have __AVR__ defined). I added in a check and #define for CORE_TEENSY to cover current and future Teensy boards, regardless of what chip they use.
