🐛 Bug Report

Array indexing allows for signed integers

transition foo()  {
        let data: [u8; 2] = [0u8, 1u8];
        assert_eq(data[-1i32], 0u8);
    }

This produces Aleo instructions, which is then rejected by snarkVM
The Leo compiler should correctly identify that this is an invalid access.
