Updated the ZFM20 class to use UART functionality provided through the
mraa::Uart class instead of using the UART directly.
* Switch to mraa::Uart
* Added raw uart string constructor, closes #621
* Updated examples
* Added a common.i to minimize interface duplication
* Removed pointers from C++ functions where references are
preferable
* Removed dependency on termios
* Added typedefs to handle pass-by-reference
* Removed flushes
* Removed code after throws
