fix(stargate/allBalances): use pagination if there are more than 100 balances

[phips28]

I have a Kujira wallet that has more than 100 balances/tokens (~116 at the time writing), therefore the allBalances function does not return all balances, only 100.

This PR changes check if there is a pagination key and gets the next page of balances.

Test I used locally:

    it("returns all balances > 100 with pagination", async () => {
      const client = await StargateClient.connect("https://rpc-kujira.synergynodes.com/");

      const balances = await client.getAllBalances("kujira1xww4yf8atl6sduqap74grkhxna5cw8r8jgw3fj");

      console.log("balances", balances);

      expect(balances.length).toBeGreaterThan(100);

      client.disconnect();
    });

But I cant add a test for it, as balances/tokens can change. If you have an idea how to add a test for it, let me know!

Hey folks, I'm from the Skip Go (formerly known as Skip API) team. This is a high priority improvement from our use case and is a big cause of customer complaints. Is there anything we can do to up-prioritize including this?
