Support `goto` statements.

Currently Selene doesn't really like my usage of goto labels, as shown below. It'd be nice if it was supported.

Relies on a full-moon update.

#229 makes this possible, though a separate PR will need to turn on lua52 feature flag.

[esatterwhite]

@Kampfkarren I'm still getting this error on 0.24.0 w/ lua52 as a base.
Is there something special that needs to be done to enable this support?

[Kampfkarren]

You need specifically a selene built with the lua52 feature flag. I'm not sure if that's available, or if that would even work.

[Kampfkarren]

It's more viable today than when this issue was first posted though

[esatterwhite]

I'd have to build one my self? do you have an example build command for this?

[Kampfkarren]

You would need to edit Cargo.toml in selene to include lua52 for full-moon

[esatterwhite]

ok. that seems to have worked. I'm not sure its entirely right.

# Cargo.toml

[workspace.dependencies]
full_moon = { version = "0.17.0", features = ["lua52"] }

#selene/Cargo.toml

[features]
default = [ "roblox", "lua52" ]
lua52 = []
tracy-profiling = ["profiling/profile-with-tracy","tracy-client"]
roblox = ["selene-lib/roblox", "full_moon/roblox", "ureq"]

[Kampfkarren]

That looks right to me, though we'd need a bit more work ourselves if we wanted to ship that.

[esatterwhite]

Is there any reason not to?
