[hpsdr] Orion_v5.2 firmware release for Orion MkI/ANAN-200D

[Joe Martin]

All, 

Apparently, neither Orion_v5.1 nor Orion_v5.2 work on everyone’s ANAN-200D universally.  For now, my recommendation for those specific cases is to revert to Orion_v5.0 firmware.  

Thanks very much for the tests and feedback.  I will continue to examine the situation to see what might be done as a remedy this frustrating issue.
