Adding support for ACE3000 Type 260

[Demel75]

Hey,

Nice job. I tried to add ACE3000 with same 2.2-protocol, only you have to do two things:

• send wake up string ("\x2f\x3f\x21\x0d\x0a" > /dev/ttyUSB0)
• use 300 baud

Baud setting seem easy, but sending the string before read - I don't really know.

Could you give a hint or help?

I start dsmr_console -v

on an othe rbash I send this:
echo -n -e '\x2F\x3F\x21\x0D\x0A' > /dev/ttyUSB0

I got this via dsmr_console then:

DEBUG:dsmr_parser.clients.protocol:got telegram: /ACE0\3k260V01.19
F.F(00)
C.1(1126130053505702)
C.5.0(01)
1.8.0(020974.0*kWh)
2.8.0(014699.9*kWh)

Would great to get this running.
Thanks in advanced.
