Query by block height

Trying to query by block height by doing the following:
```
const client = await osmosis.ClientFactory.createRPCQueryClient({
rpcEndpoint: {
url: "https://rpc-osmosis-ia.cosmosia.notional.ventures:443",
headers: { x_cosmos_block_height: "9179139" },
},
});

const pool = await client.osmosis.gamm.v1beta1.pool({
poolId: new Long(1),
})
```
but doesn't work. Can be done from CLI with
```
osmosisd q gamm pool 1 --height 9179139 --node https://rpc-osmosis-ia.cosmosia.notional.ventures:443
```
