dump1090fa: New package. Version 6.1

dump1090 from FlightAware is an ADS-B decoder
(Automatic Dependent Surveillance-Broadcast).
ADS-B is used by aircrafts to signal their presence.
Using a RTL (Realtek, very cheap) based SDR (Software Defined Radio),
you can easily build your own ADS-B decoder.

+From 059e48b82beb4fb920cca977b02db1ceb48facb9 Mon Sep 17 00:00:00 2001
+From: Oliver Jowett <oliver.jowett@flightaware.com>
+Date: Thu, 23 Sep 2021 13:23:17 +0800
+Subject: [PATCH] Allow env vars (not only command line overrides) to set
+ CPUFEATURES_{ARCH,UNAME}. Change CPUFEATURES_{ARCH,UNAME} defaults to use
+ {ARCH,UNAME} values.

+Fixes #158
