    [COMPACT][TEMP] Array compact temp fix  (#467)
    
    In the 0.1.19 patch, we changed the operator[] to return T(from const
    T). This is the right change. However, flashinfer depends on an sutble
    implicit conversion rule that requires const T behavior (which is also
    not desirable). There is a patch in flashinfer to fx this issue.
    
    This PR is a temp workaround so 0.1.19 release won't block flashinfer.
    We can reland this in next release as flashinfer's change gets into a
    release.
