Support for AVR DA Product Family

[bjburak]

Hi,

caould you please include the new DxCore boards from https://github.com/SpenceKonde/DxCore as they have support for the NEW AVR DA-series, DB-series and upcoming DD-series? I'm starting to play with these MCU's.
Installation json for arduibno is here: http://drazzy.com/package_drazzy.com_index.json

Thank you
