Haskell low level wallet crypto libraries

Adrestia libraries - Recommended for exchanges who wish to construct their own wallet scheme and manage UTXOs themselves. This consists of the following: 

• cardano-coin-selection
• cardano-addresses
• cardano-transactions
• cardano-serialization-lib
• bech32. 

The only currently available language target is Haskell, although support for JavaScript is being worked on and should be available soon.
