Shane Smiskol 922348f33d card parses radar points (#33443)
* interfaces returns radarinterface

old-commit-hash: 9ad1f096bfca3712320f19b1b49aa9e6ac9b68e4

* bump

old-commit-hash: 20334a8b257c6037e11d02f2ba7b1f02c59f3240

* get RI from opendbc

old-commit-hash: b5f6d0c48c90927926e9dd557130075aeec5edee

* stash so far

old-commit-hash: 5aa2c842eb152316434c17a661df05bb8af61f47

* new liveTracks message (radard expects and needs RadarData)

* this should just work?

* whoops

* fix that

* rm liveTracks from radard pm

* fix proceess replay

* lol fcw diff, something's not right

* actually there's fcw in original route. it's pretty close

* no tracks!

* fix test_leads

* CPU moved across procs

* fix not engageable from onroadEvents

* bump

* fixes

* bump to master

* radard publishes w/ modelV2 now, so it will always be sent. check valid which radard sets using liveTracks avg freq

* fix that (it works!)

* combine

join

* bump

* bump

* deprecate

* why

* fix incorrect args

* remove cumLagMs from process_replay

* update refs
