added USB vendor/device ID for use with and without dvb drivers

* added vendor/manufacturer id 0x1209 and product id 0x2832,
  see http://pid.codes/howto/
idea is to use modified rtl-dongle for SDR
 - without having to blacklist dvb_usb_rtl28xxu,
 that another unmodified device could be used with dvb
* added options -M and -P to rtl_eeprom for modification of USB IDs
