Kodadot mint SDK

We need a proper minting SDK:

name:

```
@kodadot1/mint
```

Architecture:

It should somehow wrap the minting logic into simple functions.
About design patterns I am thinking to use either Builder, Adapter or [Strategy](https://refactoring.guru/design-patterns/strategy).

Ref:
- https://github.com/kodadot/nft-gallery/issues/1826
- https://github.com/kodadot/nft-gallery/issues/4088
- https://github.com/kodadot/nft-gallery/issues/3976

Patterns:
- https://github.com/paraspell/sdk/pull/15

Start by reviewing the minting work described in issues #1826, #4088, and #3976, then inspect the existing repository structure and minting logic. Done means defining and implementing the @kodadot1/mint SDK API, choosing an appropriate design approach, and wrapping the minting logic into simple functions.
