Merged logging with HDLC, log and ADC protos

- New device log handler: proto_over_hdlc.cc. This sends log proto
  entries over serial in an HDLC frame.
- fpga_config/main.cc adds an ADCIdleTask to allow starting and
  stopping adc logging when pressing enter.
- Remove log statements from interrupt handlers.
- Tweak the kFramedProtoMagicConstant to remove the `~`
  character (0x7E) which is used in HDLC.
- Python changes:
  - Refactor serial parsing to separate ADC proto updates from HDLC
    wrapped log messages.
  - Binary data functions added to help with read/write buffers and
    parse varint encoding.
