[Map Instance] Expose LoadMapAsync

[Nolankicks]

For?

S&Box

What can't you do?

I'm currently working on a map voting system for my game. I want to await this in some way so my round doesn't start before the map is loaded.

How would you like it to work?

I would like it to be marked public since it is private currently.

What have you tried?

I don't believe there is a way to do this.
