CHIRP

As far as I understand, first version of this radio has been requested before, but now there is newer version out, with different contents of the EEPROM (different locations).

Both versions can be read by Chirp using BF-1909 setting.
First version can additionally be read using BF-1901 and 1904 settings.
It seems that adding these could be a relatively simple task.. (I know, I know ;) I briefly mentioned this and added files in response to issue #10138

Some of the settings that can be set in BF-1901/BF-1904/BF-1909 are not available in BF-9700.
When it comes to settings, BF-9700 is rather similar to BF-888.
It is said that BF-S56 Max is identical to BF-9700, except that it has higher rated output transistor and beefier battery.

Thank you!
