Feat: Add per-place direct join permission.

[Etheroit]

What type of feature request is this?

• Mantle doesn't support a Roblox feature I would like to use
• Mantle CLI improvement
• Other

Describe your problem
Roblox now allows enabling direct join permissions by place (instead of a global setting as previous). Should probably implement this in mantle.
