end
end
This uses a small state machine, to account for these factors to try to store only I+Q pairs:
- skip leading Q before any I
- if you get two I in a row then assume a Q went missing. Let the new I overwrite the previous data
- If you get two Q in a row then assume an I went missing. Do not store this one
Note: when you somehow detect end of input, then if last_was_I is true, you need to discard the newest stored I value, as there was no corresponding Q value found for it.
