Export hashing functions (#1275)

Browse Source 
The now-deprecated ripple-hashes library provided a number of hash
functions for users to compute the hashes/IDs for various XRP Ledger
objects:

* Transactions (to generate transaction hashes, also known as IDs)
* Transaction signing hashes (to sign transactions)
* Ledger Object IDs (to look up specific ledger objects in a ledger's
  state tree; see https://xrpl.org/ledger-object-ids.html)

This commit exports these utility methods from ripple-lib as static
methods. Access them on the RippleAPI class. Example:

import {RippleAPI} from 'ripple-lib'
const hash = RippleAPI.computeBinaryTransactionHash(...)
