Function $range

$range(start, finish, step?): Iterable<number>
Only valid as the expression of a for-of loop!

Used to compile directly to normal Lua numeric for loops. For example,
```
for (const i of $range(1, 10)) {
    print(i);
}
```
will compile into
```
for i = 1, 10 do
    print(i)
end
```
The step argument controls the amount incremented per loop. It defaults to 1.
Parameters
- start: number
- finish: number
- Optional step: number
Returns Iterable<number>
