Fix APRS-IS connection by converting host to charlist

Browse source 
The host from Application.get_env returns a binary string, but :gen_tcp.connect
expects a charlist. This was causing ArgumentError on connection attempts.

Convert host to charlist if it's a binary before passing to :gen_tcp.connect.
