[hpsdr] Angelia_v6.0 firmware for Angelia/ANAN-100D

[Joe Martin]

All, 

Angelia_v6.0 firmware for Angelia/ANAN-100D (Protocol 1) is available for download from the GitHub repository:

https://github.com/TAPR/OpenHPSDR-Firmware/tree/master/Protocol%201/Angelia%20(ANAN-100D)

This version of firmware allows the user to change the Rx5 frequency during Tx or Rx when PureSignal mode is inactive.  As before, when PureSignal mode is enabled Rx5 is dedicated to providing rf feedback to the Orion board for PureSignal support during transmit mode.
