Macro to write descriptor fragments with code

This macro will be expanded to an object of type Result<(Miniscript<DescriptorPublicKey, _>, KeyMap, ValidNetworks), DescriptorError>. It allows writing fragments of larger descriptors that can be pieced together using fragment!(thresh_vec(m, ...)).

The syntax to write macro fragment is the same as documented for the descriptor macro.
