980365097d Fix expecting string for amount types (Tobin C. Harding)
3658865a18 Fix expecting string for fee_rate (Tobin C. Harding)
d6940497fd Simplify fee_rate serde deserialize opt (Tobin C. Harding)
87d6f1718c Make serde attribute usage more terse (Tobin C. Harding)

Pull request description:

  Clean up the `serde` stuff for `FeeRate` and `Amount`. This is all pretty trivial.
