Sorokyne Tunnels Upgrade (#5020)

# About the pull request

This PR removes the five original tunnels on Sorokyne (shown below*) and
replaces them with 8 new tunnels with better placement with a focus on
the center and right side of the map.

# Explain why it's good for the game

I really like Sorokyne and I think it's a cool map, but whenever I play
Xenomorph I just hate the base tunnels on the map; two of them are right
next to comms arrays and get nuked nearly instantly, one is out in plain
view in a very high-traffic area with no cover and the remaining two are
in mediocre spots at best. The "useful" tunnels are well known by this
point.

Sorokyne's central map area (the outpost*) cannot have tunnels created
anywhere inside of it by a Burrower unlike most other maps which allow
at least some degree of indoor tunnel creation, blocking off a good
chunk of the map from having any real, useful tunnels.

I have added four maintenance hatch type tunnels to the Engineering,
Aerodome, Administration and Personal Storage areas. Three of the
remaining four have been distributed near the Research Station, east of
Carp Lake and in the far south caves to better provide access to the
cave areas.

The eight and final tunnel is in the Cryo-Thermal Springs area between
the LZs to give a movement option to the left side of the map while not
being within eyesight range of the comms array areas to prevent
Xenomorphs just tunneling straight to the array at 01:00 should it not
be destroyed already.

I believe the addition of these tunnels will help make movement around
the map more dynamic for Xenomorphs and provide them better flanking and
movement options while helping to remedy the lack of a Burrower on the
map to create tunnels.
