[Dx4win] Radio definition for IC-7300 MK2

[Max N5NHJ (I8NHJ)]

Hi Guy,
Yes, you fixed it.
It is working as expected now, I'm assuming they changed the length of 
the CI-V command response.
Didn't have time to check the manual, will do it.

I suggest you change the file name and the radio name definition to ICOM 
7300MK2, and set the default CI-V address to B6.

If you need some more testing fill free to reach out.
