New Unit: Pyke Syndicate Foot Soldiers

[bsayusd]

Description
Set up this new unit as a usable unit and include its stats and options.

Allow this unit to be selectable as a mercenary unit for the main 4 factions. This unit does not count towards the minimum, but does count towards the maximum for its type.

Describe alternatives you've considered
Should a faction have to include a second force org for mercenaries? Ideally not, as that seems to clutter lists and could make enforcing maximum unit counts harder.

Additional context
For now, this is just setting up this new unit and making available as a mercenary. Once the units are all set up, then the Shadow Collective Force Org can be created.
