Enable provider to verify lunatic attacks on consumers

## Summary

The cryptographic equivocation feature doesn't take lunatic attacks into consideration.

## Problem Definition

Currently, the provider can verify evidence of light client attacks on the consumers only for equivocation as lunatic attacks would require access to all the previous headers.

## Proposal

A suggestion is to take advantage of epochs and come up with an algorithm that enables the provider to verify evidence of lunatic attacks on the consumer.

## Task list

```[tasklist]
### Must have

- [ ] create ADR (if ADR rejected, close EPIC)
- [ ] add sub-tasks needed to implement the proposed feature
```
