Add a between(arr, lower, strict, upper, strict2) compute function

[joseph-isaacs]

Add a compute function to compute the range lower {< | <= } value {< | <=} upper where strict ==> <, and <=otherwise.

This compute function has the semantics of:

binary_boolean(
    &compare(&arr, lower, op1).unwrap(),
    &compare(&arr, upper, op2).unwrap(),
    BinaryOperator::And,
)

This has a large perf win of between 2 and 3x the above. This is due to the two comparisons and a binary and, possibly the double canonicalisation of arr.
