Z7-Lite 7020 support

zeST now supports a new FPGA board. It’s the Zynq 7020-equipped version of the Microphase Z7-Lite board, that was already supported in its 7010 version. It basically has the same capabilities of its little sister, but has significantly more FPGA logic resources available, which makes it suited for larger projects.

zeST still, and will probably remain perfectly suited for the smaller 7010 chip, though.

From now on, future releases will include configuration files for this board.
