Shapeshift native wallet integration

[0xean]

Background

Shapeshift wallet users will hopefully be some of the first users of arkeo. Many will have received arkeo from the airdrop to their etherum adresses, thorchain addresses, or cosmos address.

We will need to support airdrop related transaction in the claim module as well as core arkeo transactions that can be found in the arkeo module.

claim proto

Acceptance Criteria

1. SS Native wallet users are able to sign transactions using either the comsos or thorchain derivation paths / coin types.
2. SS Native wallet ethereum users can sign a eth message (EIP 712) (I assume this is already supported)
