Query unpacking is slow

[Ukendio]

From #28

The unpacking of the columns is very expensive and is a large part of the queries overhead. This is in general a problem with a lack of good iterators in luau, and unless theres tuples or array destructering introduced the only reasonable solution we can do at the user-space level is to enable optimizations for hotpaths by inlining indexes into the columns.
