	 * Now we are ready to parse OTP memory content.

	 * OTP data start from a fixed size header that is followed by a several
	 * data containers of a variable size. Data containers are stored in a
	 * stream like format: each container (stream) begins with a predefined
	 * one octent lenth marker, that is followed by a stream header and
	 * data, and then stream is finished by an end marker of two identical
	 * octets. Sream length are never stored, instead the stream length
	 * should be calculated as a difference between the 'end' and 'begin'
	 * markers.
	 *
	 * Each (begin/end) marker consists of a constant (high nibble) and
	 * variable (low nibble) parts. Constant part is different for begin
	 * and for end markers, but stay the same for different streams. While
	 * variable part should be identical for begin and for end markers of
	 * item stream, but could differ from stream to stream. Looks like
	 * the variable part of marker is used to avoid false positivie end
	 * marker detection. I.e. OTP writing sofware selects value for the
	 * variable part in a such way that avoids appearing of double end
	 * marker in the stream data. But we should not care, since we should
	 * just parse this. So parser extract a value of the variable part
	 * (lets call it a stream code) of the begin marker and then looking
	 * for the end marker by checking each next octet of OTP for the
	 * constant part of the end marker and for variable part (stream code)
	 * that was extracted from the begin marker.
