Documentation TODO
Mention it uses BigInt (for checksums)
If BigInt support is not possible, then remove the checksum before passing the descriptor to the parse function.
Document that it supports all SCRIPT expressions, including also all possible miniscript, but it does not support raw(), combo(), sortedmulti(), tr(), multi_ (taproot), sortedmulti_a (taproot), rawtr (taproot)
no need to mention multi_a or sortedmulti_a since they must be inside tr( anyway
~document we do not support multiple wildcards yet (not sufficiently specified in official docs).~
document we do not support bare multi. In fact, it may lead to several resource limitation probs. Better to use multi within sh or wsh, sh(wsh anyway.
document the test/tools folder (generate bitcoin core fixtures)
