Version 0x04

Changes

• added RF_Config.h for the user to enable/disable protocols needed
  This action is required because of the limited flash space.
  Each user can set the protocols he wants and compile a new HEX file for flashing
  Also the bucket sniffing can be disabled by compiler flag to save 1159 bytes of flash
  Right now all protocols and bucket sniffing is included. 485 bytes are left...
• added a Check_Size.py script to check if the compiled HEX file will match to the EFM8BB1 size
• some bugfixing on sniffing commands
• moved high/low bucket marking to the protocols
• added support for "end" buckets
• added Kaku protocol
