Notes:
Header uses the longer lead-in while data areas use the shorter.
Duration of lead-in pulses is also longer than the 1-bits of the payload, lead-ins are in the range 0x038C-0x03DA.
First pulse shorter than lead-in duration belongs to the first data byte.
Header:
Header is a separate file and always loads to 0x033C-0x0350
00 Secondary address
01-02 Load start address (Low/high order)
03-04 Load end address (Low/high order) (Inclusive)
