There's a couple of instances of code paths where we are recomputing the public key when we have already computed it one scope up. One instance of this is [here](https://github.com/MetaMask/key-tree/blob/0a2faf3aacf931876bd18c61055cde715606f76b/src/derivers/bip39.ts#L170) and [here](https://github.com/MetaMask/key-tree/blob/main/src/SLIP10Node.ts#L315), but I believe there are others too. This is worth revisiting for performance reasons.
