Safelight missing exec function for erc4337

[drortirosh]

I looked at your Safelite implementation
It does have validateUserOp, so it can be used with erc 4337 bundlers.
However, it misses an "execute" function.
You can use "multiSend" but that would require double signature.
I suggest adding execute and executeBatch methods that require msg.sender==entrypoint
