Descriptor checksum doesn't match bitcoind

[bodymindarts]

Describe the bug
Descriptors generated via bdk cannot be imported into bitcoind due to checksum mismatch.

To Reproduce
I have documented a reproduce here as part of #967

I try to import the descriptor from here into a bitcoind running on regtest but it won't.

Expected behavior
I would expect to be able to import the descriptor.

I was able to repro that if you add with ' or h bdk always converts first to ' and compute the checksum from that. To match with core's checksums you'll need to use ' in your descriptor string.

    #[test]
    fn test_hash_vs_tick() {

        let secp = Secp256k1::new();
        let network = Network::Regtest;

        let descriptor1 = "pkh(tpubD6NzVbkrYhZ4XHndKkuB8FifXm8r5FQHwrN6oZuWCz13qb93rtgKvD4PQsqC4HP4yhV3tA2fqr2RbY5mNXfM7RxXUoeABoDtsFUq2zJq6YK/44'/1'/0'/0/*)";
        let descriptor2 = "pkh(tpubD6NzVbkrYhZ4XHndKkuB8FifXm8r5FQHwrN6oZuWCz13qb93rtgKvD4PQsqC4HP4yhV3tA2fqr2RbY5mNXfM7RxXUoeABoDtsFUq2zJq6YK/44h/1h/0h/0/*)";

        let (descriptor1, _keymap) = descriptor1.into_wallet_descriptor(&secp, network).unwrap();
        let (descriptor2, _keymap) = descriptor2.into_wallet_descriptor(&secp, network).unwrap();

        //println!("descriptor1: {}", descriptor1);
        //println!("descriptor2: {}", descriptor2);
        assert_eq!("pkh(tpubD6NzVbkrYhZ4XHndKkuB8FifXm8r5FQHwrN6oZuWCz13qb93rtgKvD4PQsqC4HP4yhV3tA2fqr2RbY5mNXfM7RxXUoeABoDtsFUq2zJq6YK/44'/1'/0'/0/*)#lasegmfs", descriptor1.to_string());
        assert_eq!("pkh(tpubD6NzVbkrYhZ4XHndKkuB8FifXm8r5FQHwrN6oZuWCz13qb93rtgKvD4PQsqC4HP4yhV3tA2fqr2RbY5mNXfM7RxXUoeABoDtsFUq2zJq6YK/44'/1'/0'/0/*)#lasegmfs", descriptor2.to_string());
    }

Yup confirmed - its just not intuitive when looking at the tests (as they use h).
