Remove an element from a vector set.

```shell
VADD vset VALUES 3 1 0 1 bar
(integer) 1

VREM vset bar
(integer) 1

VREM vset bar
(integer) 0
```

`VREM` reclaims memory immediately. It does not use tombstones or logical deletions, making it safe to use in long-running applications that frequently update the same vector set.
