computeLedgerHash: support new getLedger response by using
rawTransaction
BREAKING CHANGES:
* Remove the `rawTransactions` field and replace it with a new `rawTransaction` field in each transaction.
* Rename the `metaData` field (in each raw transaction) to `meta` (for consistency with rippled's `tx` method).
* Add `ledger_index` to each raw transaction.
The 'amount' field should almost never be used.
With partial payments, the field can show an amount that is
significantly less than the amount that the transaction actually
delivered. This change sets amount to 0 XRP when it may be misleading.
This change omits the `amount` when parsing payment transactions.
See `HISTORY.md` for recommended alternatives.
* Add maxFeeXRP (default 2 XRP) as an optional RippleAPI constructor parameter
- No calculated or specified fee can exceed this value
- If the fee exceeds 2 XRP, throw a ValidationError
* sign() - throw ValidationError when Fee exceeds maxFeeXRP
* Document getFee parameters
* Explain new fee limits in HISTORY.md
* Deprecate `maxFee`
- `RippledError`: Include the full response from the `rippled` server.
- A new test ensures correct behavior when `streams` is not an array.
- `NotConnectedError` may be thrown with a different message than before.
