Pieter Wuille	7cedafc541	Add tr() descriptor (derivation only, no signing) ... This adds a new descriptor with syntax e.g. tr(KEY,{S1,{{S2,S3},S4}) where KEY is a key expression for the internal key and S_i are script expression for the leaves. They have to be organized in nested {A,B} groups, with exactly two elements. tr() only exists at the top level, and inside the script expressions only pk() scripts are allowed for now.	2021-05-24 12:14:16 -07:00
