closes #166 closes #162

Merging this change directly into `master` to make the diff of #236 easier to read.

Allow custom storage slots

A function like this must be added to each storage library: ```solidity function layout(bytes32 slot) internal pure returns (Layout storage l) { assembly { l.slot := slot } } ```

Use EIP-7201 to define storage slots

[This EIP](https://eips.ethereum.org/EIPS/eip-1967) uses `keccak256` to generate storage slots, and subtracts 1 from the result to avoid preimage attacks. This works for the EIP because it uses only single-slot storage values,...

On the surface, this is not a good idea. But I think it would be worth it for most IMT use cases.
