v2.0.1

Fixed part designation on op-amps. Replaced tl072 with lm4562 for simpler BOM.
Added LED indicators on MCU
Added RTC crystal, moved DIT and DAH to port B.
Added thermistor to measure PA temperature
Changed low-pass in PA to 5th-order elliptic
Reduced capacitance of C406 due to mosfet drain capacitance
