New IC-7300 .xml file

[John at <kb0...@gm...>]

Maybe this is old news.   At any rate I downloaded the IC-7300.xml file on
the git.hub and tried to open it with gedit  and Firefox xml reader and I
had parsing errors.   I went ahead and corrected some errors in the file
and got it to open correctly.   I'm not sure if the errors actually affect
the files operation in fldigi.

I am attaching the revised file for your evaluation.   Hopefully it goes
through.
