feat: add vm.loadAllocs(string) cheatcode (#474)

* vm: add `loadAllocs(string)` cheatcode Adds the `loadAllocs(string)` cheatcode to be usable as part of the `Vm` interface. This was added to foundry in foundry-rs/foundry#6207. The cheatcode can be used to read a JSON file from disk that sets EVM state directly. * chore: keep section alphabetically sorted --------- Co-authored-by: Matt Solomon <[email protected]>
