I was playing around with a probably-too-cute script for LN channel smart contract, and was looking for something to decide for me if miniscript can infer the structure of the script.

f.e.

```
decodescript 82012088a914ffffffffffffffffffffffffffffffffffffffff8820ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffad51b2

{
  "asm": "OP_SIZE 32 OP_EQUALVERIFY OP_HASH160 ffffffffffffffffffffffffffffffffffffffff OP_EQUALVERIFY ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff OP_CHECKSIGVERIFY 1 OP_CHECKSEQUENCEVERIFY",
  "desc": "raw(82012088a914ffffffffffffffffffffffffffffffffffffffff8820ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffad51b2)#5guaahuv",
  "type": "nonstandard",
  "p2sh": "33YyjgxsJYwSi8Wbp7TaCSFAuJBoUfYWDQ",
  "segwit": {
    "asm": "0 99f5d0b69f9828fea9363198cf812e95d7fc5e94c7881092b8e3f43984c1bd5c",
    "desc": "addr(bc1qn86apd5lnq50a2fkxxvvlqfwjhtlch55c7yppy4cu06rnpxph4wqrar3md)#wtlf0gwk",
    "hex": "002099f5d0b69f9828fea9363198cf812e95d7fc5e94c7881092b8e3f43984c1bd5c",
    "address": "bc1qn86apd5lnq50a2fkxxvvlqfwjhtlch55c7yppy4cu06rnpxph4wqrar3md",
    "type": "witness_v0_scripthash",
    "p2sh-segwit": "3MRJN2wTnD2BVm31HLcBwueAYpbbximrtk"
  }
}
```

Since it's evaluated at "top level for `desc` it cannot get any meaningful structure from it. Perhaps in `segwit` it could try infering the miniscript in the segwit context


{
    CDataStream ssTx(SER_NETWORK, PROTOCOL_VERSION | serializeFlags);
    ssTx << tx;
    return HexStr(ssTx);
}
void ScriptToUniv(const CScript& script, UniValue& out, bool include_hex, bool include_address)
{
    CTxDestination address;
    out.pushKV("asm", ScriptToAsmStr(script));
    if (include_address) {
        out.pushKV("desc", InferDescriptor(script, DUMMY_SIGNING_PROVIDER)->ToString());
    }
    if (include_hex) {
        out.pushKV("hex", HexStr(script));
    }
    std::vector<std::vector<unsigned char>> solns;
    const TxoutType type{Solver(script, solns)};
    if (include_address && ExtractDestination(script, address) && type != TxoutType::PUBKEY) {
        out.pushKV("address", EncodeDestination(address));
    }
    out.pushKV("type", GetTxnOutputType(type));
}
void TxToUniv(const CTransaction& tx, const uint256& block_hash, UniValue& entry, bool include_hex, int serialize_flags, const CTxUndo* txundo, TxVerbosity verbosity)
