[Request] Version control of adaptive link

1. alink_drone 27b8af47c1fbc91b8a20afd899827583 --> stucked "initializing... 6.3Mb FPS:60 54% tx34c rssi-44, snr15 fec1 pnlt0 xtx0 i" #17
2. latest binary version: b74d37a8c4696762fab7dd2e86296ec0

I got below error:

root@openipc-ssc30kq:~# /usr/bin/alink_drone --ip 10.5.0.10 --port 9999
Warning: Unrecognized configuration key: allow_set_power

I found it's handled by latest code:

https://github.com/sickgreg/OpenIPC-Adaptive-Link/blob/009df32429b8ad54608b86bb7fa7cda401325e91/alink_drone.c#L215

Finally, I got compiled binary #13 + altered config, then it works.

But I still don't know if it's suitable for 800mW, any difference with 2W? #16
