Airspy Firmware version v1.0.0-rc10-6

This release improves the overall phase noise, tuning accuracy, dynamic range and spur responses.
What changed:

• More accurate R820T/2 tuning.
• Fast R820T/2 register update by only sending the actual changes. Useful for fast scanning.
• The R820T/2 reference clock is now fed directly from the 25 MHz TCXO. No noise contribution from PLL_A at all when using the internal TCXO.
• The MCU and ADC reference clock is now using PLL_B of Si5351 in Integer mode with power of two dividers.
• EXT_CLK now feeds PLL_A for the R820T/2 and PLL_B for the LPC4370 with optimal Integer Mode and power of two dividers.
• Drive level reduced to 2mA per clock. This significantly reduces the spurs.

For flashing under Windows:
