RE Mote: Enhancements from Rev.A to Rev.B

These are the most important enhancements from Revision A:

• Replaced "Low Power PIC" PIC12F635 for PIC16F1509, to extend the number of pins and peripherals
• Simplified "shutdown mode" operation, now commands are sent over I2C to the "Low Power PIC"
• PIC low power now is powered over battery and USB, solving an errata in battery management
• NanoTimer (TPL5110DDCT) was removed and now shutdown scheduling is managed by the RTCC and PIC low power.
• Replaced LED RGB (ASMB-MTB0-0A3A2).
• RTCC Interrupt 1 is now connected to PD3 pin from CC2538.
• Added battery monitoring via the "Low Power PIC", readable over I2C command.
• Improved noise prevention in USB transmission lines.
• Changed I2C Interrupt/Generic pin to PD0 from CC2538.
• Mapped TDI and TDO pins to LED's to save more pins, the LEDs can be disabled if needed by desoldering a resistor.
• ADC3 (5VDC supply voltage) impedance was improved
• Changed CC1200 LDO to provide a 3.3V supply instead of 3V.
• Fixed silkscreen pinout assignations.
• Added 1 extra pin exposed on each external connector (JP5 and JP6)
• JTAG pins (TMS, TCK) are not exposed on lateral connectors, just only through the JTAG connector.
• Pitch between external connectors are now 2.54 mm multiple, compatible with most protoboards.
• Modified Battery pin-out orientation over an additional connector, to allow connect the battery with a standard connector and place inside the RE-Mote enclosure
• Improved labelling on PCB for correct indication to user (USB and switch indicators, ...).
• PA6 and PA7 mapped to the microSD SEL/CSn are exposed in the JP5 connector, to allow use as ADCx/AINx if a 0Ohm resistor is removed
