Describe the bug

import {ssz} from "@lodestar/types";

const {BeaconState} = ssz.phase0;
console.log(
  BeaconState.getPathInfo(["validators", 0, "activationEpoch"]).gindex === BeaconState.getPathInfo(["validators", 0, "pubkey"]).gindex
);
// true

Expected behavior

false

Currently running into this - how do I calculate the gindices of these fields manually?

Trying to generate a merkle proof of these fields, but can't do so if the gindices are the same for the Validator container, as well as all of the fields within it.

# Changes
- Add a `DivaBeaconOracle` contract where you can prove:
- Any of the fields of a
[validator](https://github.com/ethereum/consensus-specs/blob/dev/specs/phase0/beacon-chain.md#validator)
- The `balance` of a validator using the `balances` container in
`BeaconState`
- A deposit from a BLSPubkey using the `deposits` container in
`BeaconBlock`

# Notes
Lodestar currently has a [gindex
issue](ChainSafe/ssz#311) for fields in the
`Validator` container. As such, we need to calculate the gindices of
`Validator` fields manually.
