Telegrams w/o CRC, Kilo, *255

[Aeroid]

Is your feature request related to a problem? Please describe.
The DSMR parser currently seems to

• require CRCs
• assumes "kW" only (i.e. ignores "W" units) and
• stumbles over "*255" suffix to the OBIS code

Telegrams like this don't work:

 /ESY5Q3DB1024 V3.04

1-0:0.0.0*255(0272031312565)
1-0:1.8.0*255(00066982.7369255*kWh)
1-0:2.8.0*255(00025261.5976087*kWh)
1-0:21.7.0*255(000210.92*W)
1-0:41.7.0*255(000225.08*W)
1-0:61.7.0*255(000144.75*W)
1-0:1.7.0*255(000580.75*W)
1-0:96.5.5*255(80)
0-0:96.1.255*255(1ESY1313002565)
!

Describe the solution you'd like

• Parse units w/o kilo correctly
• Accept CRC-less telegrams
• Accept "*255" suffix to the OBIS codes

Describe alternatives you've considered
My current workaround is parsing above telegrams and re-assembiling them in evcc-dsmr
The workaround can be found here: https://github.com/Aeroid/dsmr-tools as a python tcp bridge. It also includes a few more dumped telegrams.
