add indexer gateway client

[xiam]

This PRs adds the TypeScript client for Indexer Gateway.

[xiam]

This example:

import {
  SequenceIndexerGateway
} from '0xsequence/indexergw'

const ACCOUNT_ADDRESS = '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48'

const indexerGateway = new SequenceIndexerGateway(
  API_URL,
)

indexerGateway.getNativeTokenBalance({
  accountAddress: ACCOUNT_ADDRESS,
}).then((res:any) => {
  res.balances.forEach((balance:any) => {
    console.log({balance})
  })
}).catch((error:any) => {
  console.log({error})
})

Prints:

{
  balance: {
    chainID: 42170,
    balance: {
      accountAddress: '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48',

Could we include the indexer gateway within the existing indexer package instead of creating a new one

[corbanbrook]

Also looking at the output seems like there is redundant wrapping of balances:

{
  balance: {
    chainID: 11155111,
    balance: {
      accountAddress: '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48',
      balance: '11164700846227378526'
    }
  }
}

balances[0].balance.balance.balance

this could just be:

{
  chainId: 11155111,
  accountAddress: '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48',
  balance: '11164700846227378526'
}

please lets not introduce another "indexergw" package. I know we are doing this on the Go side, but I don't want to do this on the Typescript side.

Please instead keep everything in @0xsequence/indexer and just have packages/indexer/src/indexer.gen.ts and packages/indexer/src/gateway.gen.ts and then for index.ts we can export separately or even we can use the "exports" so developers can import { IndexerGatewayClient } from '@0xsequence/indexer/gateway' as an example. But also could also do: import { IndexerGatewayClient } from '@0xsequence/indexer' ... we could export as .... from index, and bunch of other options.. but lets not introduce "indexergw" package here.

@corbanbrook This is how output from the latest version looks:

[
  {
    chainId: 10,
    result: {
      accountAddress: '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48',
      balance: '371086549230872066'
    }
  },
  {
    chainId: 81457,
    result: {
      accountAddress: '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48',
      balance: '0'
    }
  },
  {
    chainId: 137,
    result: {
      accountAddress: '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48',
      balance: '52408389691068799440368'
    }
  },

@corbanbrook I fixed the spelling for the newly introduced chainId properties; I'll tackle the legacy ones in a follow-up PR.

This was already done
