PMG512DAC and 256DSD Support

Just downloaded this but have not updated. @Paul the new firmware is for the PMG 512 DAC. It’s mislabeled for the pre.

From the downloaded ZIP file on my PC.

From the PDF release notes. This is the sample rate display update many have asked for.

*Edit: Firmware and streamer updated…see, Firmware update for PMG 512 DAC - #25 by jaycee
