How to get length of parsed packet?

[blowback]

Given a PacketRef obtained from a parser iterator, how do you get the packet's original encoded length? There's a class_and_msg_id() method on PacketRef, but I don't see anything similar for length (bytes at offsets 4 and 5).

@blowback,

We have no means to expose such information in the current state, when dealing with complex packets whose size may vary.
With simplistic packets, you have UbxPacketMeta::FIXED_PAYLOAD_LEN.
To answer that requirement, pack_len here should be saved in the packet being constructed
