A list of the changes included in this build (since the last daily)
follows:

Changes for Build #564
[Dan Smith <dsmith at danplanet.com>] Fix exposing proper tuning steps for UV3R

Fixes #6519

[Jim Unroe <rock.unroe at gmail.com>] [UV-5X3] Add additional supported STEPS

Add 20.0 KHz and 50.0 KHz steps that are also supported by the BTech UV-5X3.

This patch and the previous patch also fixes the "STEP" issue for other
Baofeng and BTech radio models whose drivers use baofeng_common.py (such
as the Baofeng UV-6R, Baofeng WP970i variants such as the GT-3WP, BTech
GMRS-V1 and BTech MURS-V1).
