Updated GetRecentBlockHash to GetLatestBlockHash (#56)

* Updated GetRecentBlockHash to GetLatestBlockHash instances on the Solana RPC Client. Included core code and tests, but left interface-instances for convenience.

* Explicitly awaiting GetLatestBlockHash everywhere

* Changed explicit variabled typing to implicit, on request of magicblocks team.
