Label 1L decoding

[makrsmark]

I hate the class names. open to suggestions

[makrsmark]

@rpatel3001 - not sure if the positions line up with what acars2pos has

"1L": [compile(dlat + d2("latdeg") + d2("latmin") + d1("latmin10") + dlon + d3("londeg") + d2("lonmin") + d1("lonmin10"))],

I'm guessing i'm missing a type?

[kevinelliott]

Ha, I hear you. I have no better suggestion.

Btw, coords have me thinking that maybe we need to eventually add a raw/formatted value that indicates if a location is current, past, future/planned, etc. Some kind of indication whether or not the value is useful for plotting now or part of a plan/estimate, etc.

Looks good to me.

So far when raw.position is set, it's a current timestamp. it can be a couple of seconds old, but if i set message_timestamp, that doubles as a 'position valid time'. Otherwise, the message received time (outside of this library) is the best guess

[kevinelliott]

What I mean is the intention of the position. Some positions are stale by hours and may not indicate a "now" position, and some positions/waypoints are in the future for estimates, route planning, or unexpected route updating. Would be good for us to eventually classify these so we know what the intention of the position is.

I have a couple more formats in my logs, plus it looks like a couple extra in the docs, plus more field definitions for the 3 line format.

Thanks @rpatel3001 ! I'll add some specs and the variant you're parsing

[makrsmark]

Going to leave some of the 3-line attributes in "unknown" despite mostly knowing what they are since i don't want to think about it (i know, i know)
