Export transfer functionality as a separate sdk

[Szegoo]

Since this project essentially supports all types of token transfers that can occur in the Polkadot ecosystem without being specific to the underlying blockchain implementation, it could be of great use for anyone building apps in the Polkadot ecosystem to easily integrate token transfers.

Particularly it allows the following types of token transfers:

• Native token transfers
• Native token transfers using XCM
• Reserve transfers
  • Reserve transfers where the origin chain is the reserve
  • Reserve transfers where the destination chain is the reserve
  • Reserve transfers where a foreign chain is the reserve of the asset. This is referred to as a Two-hop XCM reserve transfer.
• Teleport transfers

The code is also capable of determining on its own which of these token transfers needs to be utilized for a successful transfer.
