Change frequency range of FM RADIO from 76–108 MHz to 87-108MHz

[pdrbsts]

In my country at least there are FM stations broadcasting from 87.5 MHz. Please add the option to change the lower FM limit from 76 MHz to 87 MHz.

if fw[0x6452] == 0x5F: print('Changing lower FM RADIO limit from 76 to 87...') fw[0x6452] = 0x6D

Thank you.
