New features
- Add support for JSON-style transaction metadata (see documentation for more detail)
- Improved error handling on non-WASM targets
- Remove wasm-bindgen as a dependency for non-WASM targets
- add a
add_inputfunction that takes an address and figures out how to handle it internally instead of having the user do it - add a
fee_for_inputthat says how much the fee would increase by adding an input. This is useful for input selection since you can avoid adding inputs where the value of the input is less than the fee to add it.
