Added getTransaction and getTransaction receipt functions

[dribeiro-ShardLabs]

Usage related changes

• Implement getTransaction and getTransactionReceipt functions for the starknet object

Development related changes

• GetTxStatusWrapperOptions type was changed to a more generic TxHashQueryWrapperOptions, because there are now multiple functions that use the same structure for transaction hash based queries:
  -- prepareGetTxStatusOptions was changed to prepareGetTxQueryOptions, and now takes an additional argument command as a parameter;
• L1Message and L2Message types were changed to L1ToL2Message and L2ToL1Message respectively to be more clear;
