feat: disable root (#1481)

**Motivation:**

We want to be able to disable a root in case of malicious activity. Here
is the state diagram (we're still evaluating pausers):

**Modifications:**

- Add disable functionality in `OperatorTableCalculator`. Only
previously posted, valid roots, can be disabled
- Certificate verifiers check `isRootDisabledByTimestamp` to see if root
is valid
- Update typeHash to include `referenceBlockNumber`

**Result:**

Secure code.
