ATG Garmin Vitals for ACE

Adds a vitals screen to the RHS Garmin wrist watch, reading heart rate and
blood pressure from ACE Medical. Cycle to it like any other watch mode.

- The watch switches to vitals by itself when the wearer's heart rate or
  blood pressure leaves the configured bounds, and switches back once both
  return to range.
- The low blood pressure threshold sits at hypotension onset rather than the
  shock line, so it warns before a wearer collapses rather than as they do.
- An optional buddy alert beeps and flashes the watch when a nearby friendly
  goes out of bounds, so a casualty who cannot call out is still noticed.
  Both parties need a watch. Off by default - it costs a periodic proximity
  sweep while anyone is down, enabled only by Server Owner.
- Every threshold, range and period is configurable per server. Settings no
  client reads stay on the server, so they cost a joining player nothing.

HOW THE BUDDY ALERT HANDLES DEATH

A casualty who dies flashes once and their highlight clears, so you are told
the outcome rather than left with a warning that never goes out. Anyone else
still down causes your watch to have a red tint, and flashes again if they die.

Somebody nearby that is killed outright also flashes, even though they were 
never "in distress" at any instant.

You are never your own buddy. The alert is one watch telling its wearer about
somebody else, so a single player cannot test it alone - and carrying two
watches does not get round it, because both are on one person.

OTHER MODS CAN READ THE VERDICT

A wearer's state - unconscious, dead, or neither - is readable by any mod loaded after this
one. ATG Signals uses it to carry a casualty's condition across the position network, so a
marker can show that somebody is down and not only where they were.

The verdict is the same one the buddy alert uses and is deliberately narrow: down means
unconscious, not merely hurt. It is readable whether or not the buddy alert is switched on -
that setting governs the beep and the overlay, not the reading.

This works by LOAD ORDER, not by a declared dependency. Order ATG Garmin Vitals for ACE
BEFORE ATG Signals in your mod list. With the order wrong, the feature compiles out
silently, nothing errors,.

LOAD ORDER

RHS and ACE Medical must load before this mod and are declared dependencies. 
Load ATG Core before it as well for per-server JSON settings; without
ATG Core the mod runs on its own built-in defaults.
