[ft2900] Support Euro version of FT-2900/FT-1900 (#2501)
This patch adds support for the Euro version of the FT-2900/FT-1900
radio, which uses a different header IDBLOCK than the US version.  We
make the IDBLOCK a class variable, and then create a subclass for the
Euro version, with an override to the IDBLOCK.
