Summary0007916: support STEFAN parameters [estimate: 20h]
DescriptionThe exchange /keys response now contains stefan_abs, stefan_log and stefan_lin as per DD47. The wallet (core) should compute fees according to the STEFAN curve and pass the values to the UIs.

The wallet should also add code to compute default STEFAN curve values from the fee structure. A CLI command should output these values given an exchange base URL. The exchange configuration documentation should be updated to explain when and how to run the tool.

The computation could also be used by the UIs if a user requests a fee comparison to protect users against exchanges with dishonest STEFAN values. However, the computation MAY be to expensive to run on a regular basis by the wallet (TBD). Exchanges MAY also be configured with higher STEFAN values than those obtained from the wallet directly.
