[wireless-regdb] [PATCH] wireless-regdb: Support db.txt files with DFS CAC times

[Seth Forshee]

CRDA now supports db.txt files with DFS CAC times in country
rules, but dbparse.py chokes on such files. We can't do
anything useful with CAC times right now since the CRDA
binary format doesn't support them, so add code to parse CAC
times and emit a warning that they are being ignored.

I'm throwing this out there in case anyone wants to build regulatory.bin
files from their own db.txt files which contain CAC times. If so, let me
know and I can apply this.

Jean-Pierre: This is working fine in my testing. Could you give it a try
with your file(s) and let me know how it works?
