error notes.txt

message type 31 is truncated at 2330970 in the middle of a dzdr block
after parsing a message type the next expected data should be verified first before commiting the data from the previous block
if theres an error discard the previous block and go back to the last known good position to search for:
			message_size: raf.readShort(),
			channel: raf.readByte(),
			message_type: raf.readByte(),
			id_sequence: raf.readShort(),		// should be known - jumps by 6 in this case
			message_julian_date: raf.readShort(),	// likely known or +1
			message_mseconds: raf.readInt(),
			segment_count: raf.readShort(),	// 0x01
			segment_number: raf.readShort(), // 0x01

			id: raf.readString(4),
		mseconds: raf.readInt(),
		julian_date: raf.readShort(), // likely known or +1
		radial_number: raf.readShort(), // jumps by 6 
		azimuth: raf.readFloat(),	// = 265-268 // jumps by 6 at 0.5 degree interval
		compress_idx: raf.readByte(),
		sp: raf.readByte(),
		radial_length: raf.readShort(),
		ars: raf.readByte(),
		rs: raf.readByte(),
		elevation_number: raf.readByte(),
		cut: raf.readByte(),
		elevation_angle: raf.readFloat(),
		rsbs: raf.readByte(),
		aim: raf.readByte(),
		dcount: raf.readShort(),

		best option appears to be searching for:
		julian date (2 bytes), known value, or known value plus 1
		message mseconds (4 bytes), don't care
		segment count and number = 0x0001 0x0001
