Yet another update today !

Changes to this version are as follows.
Note.
Because of the change to keep the calibration table for all radios in the same location, I've updated the CPS to handle this

Changes to this version are as follows.
- The firmware makes a copy of the calibration table and saves it at address 0xF000 in Flash. This change was made so that the DM-1801 and GD-77 calibration table can be at the same address and only one CPS is then needed for both radios. (Note the DM-1801 version also has to copy the calibration to 0xF000 but its original location is different from the GD-77 calibration table
- Speed of access to the Flash memory has been improved by the removal of some redundant code, which kept checking if the Flash was busy
- Improve boot speed, by removal of the 500mS delay at the start of the code, which no longer seemed to be needed. (You probably won't notice this change)
- Updated translations for some languages, for the new Sound Options menu
- Scan option in the VFO quick menu can now be activated by pressing the Orange button again (like on the Channel screen)
- Location of the Scan option has been moved to make it easier to get to in the VFO quick menu (and on the DM-1801 the VFO quick menu Scan option is in the same location in the menu as on the Channel screen, because the DM-1801 does not need the option to change VFO, as it has a separate button "A/B" for this.
- Screen backlight PWM frequency has been increased from 2.4kHz to 10kHz, because on the DM-1801 a 2.4kHz tone could be heard through the speaker when the backlight was on. (I don't recall hearing this on the GD-77, but it may cause a slight improvement on the GD-77 even if the sound was at a sub-audible level)
