@brief Create RMT BitScrambler encoder

@note The BitScrambler encoder is used to encode the user data into RMT symbols by providing the BitScrambler assembly program. The BitScrambler program is a binary blob, it should take control of the whole encoding stuffs, including inserting the EOF marker.
