Safe x Scroll: l1sload module demonstration

This project demonstrates a basic use-case where a safe on a Layer2 safe(L2) inherits its keystore (configuration/security policy: owners and threshold) from a Safe on a Layer1 safe(L1) via a Safe module SafeRemoteKeystoreModule enabled on safe(L2).

This Module can optionally set a guard to prevent safe(L2) to use its local keystore and only enable the remote keystore of safe(L1) as valid keystore.

It leverages a precompiled contract called l1sload to load a storage slot on the L1 chain (see L1SLOAD spec).
