[hpsdr] Angelia_v5.8 (protocol1) firmware available for Angelia/ANAN-100D

[Joe Martin]

All, 

Angelia_v5.8 (protocol1) firmware is available for download from 

https://github/TAPR/OpenHPSDR-Firmware

This current-protocol (protocol1) version upgrades to Quartus Prime Lite v16.1, replaces all megafunctions to QPL v16.1 versions, implements peak detect for FWD_PWR (AIN1) and REV_PWR (AIN2) to settle SWR readings in software, and fixes a bug in the external PTT IN (pin 13 on the accessory jack of ANAN-100D).
