Notes:
Tactic Documentation:
## Tactic lia2card
### Short Description
Extract 0-1 integer variables used in
cardinality and pseudo-Boolean constraints and replace them by Booleans.
### Example
```z3
(declare-const x Int)
(declare-const y Int)
(declare-const z Int)
(assert (<= 0 x))
(assert (<= 0 y))
(assert (<= 0 z))
(assert (>= 1 x))
(assert (>= 1 y))
(assert (>= 1 z))
(assert (>= (+ (* 5 x) (* -2 z) (* 3 y) 1) 4))
(apply lia2card)
```
### Notes
* The tactic does not (properly) support proofs or cores.
