Access API response types in client v2

**Is your feature request related to a problem? Please describe.**

In v1 we were able to use the following type

```ts
import type { FtMetadataResponse } from "@hirosystems/token-metadata-api-client";
```

In v2 I didn't find a way to access the types from the client SDK.

**Describe the solution you'd like**

Same feature as v1
