Fee estimate

Receive a fee estimate for a transaction.

Send a serialized transaction and receive back a naive fee estimate. Note: partialFee does not include any tips that you may add to increase a transaction's priority. See the reference on compute_fee. Replaces /tx/fee-estimate from versions < v1.0.0.
