The `reference-trie` version 0.29.1 on crates.io refers to an older version.

The reference-trie version 0.29.1 on crates.io is using an older version of trie-db (0.27.0), which is inconsistent with the version specified in the Cargo.toml file. This inconsistency may lead to ambiguity when importing external crates.

trie/test-support/reference-trie/Cargo.toml

Line 13 in 6eb4b88

trie-db = { path = "../../trie-db", default-features = false, version = "0.28.0" }

I tried to import reference-trie 0.29.1 and trie-db 0.28.0 into my code and wrote a demo, but I encountered a compilation error.
demo:

use hash_db::Hasher;
use memory_db::{HashKey, MemoryDB};
use reference_trie::{RefHasher, RefSecTrieDBMut, RefTrieDBBuilder};
use trie_db::{DBValue, Trie, TrieMut};

fn main() {
    let mut memdb = MemoryDB::<RefHasher, HashKey<_>, DBValue>::default();
    let mut root = Default::default();
    {
        let mut t = RefSecTrieDBMut::new(&mut memdb, &mut root);
        t.insert(&[0x01u8, 0x23], &[0x01u8, 0x23]).unwrap();
    }
    let t = RefTrieDBBuilder::new(&memdb, &root).build();
    assert_eq!(
        t.get(&RefHasher::hash(&[0x01u8, 0x23])).unwrap().unwrap(),
        vec![0x01u8, 0x23],
    );
}

compilation error:

   --> src/main.rs:12:11
    |
12  |         t.insert(&[0x01u8, 0x23], &[0x01u8, 0x23]).unwrap();
    |           ^^^^^^ method not found in `SecTrieDBMut<'_, ExtensionLayout>`

The reason for the error is that the version of trie-db used by the reference-trie crate is 0.27.0, which conflicts with the version specified in the Cargo.toml file mentioned in

trie/test-support/reference-trie/Cargo.toml

Line 13 in 6eb4b88

trie-db = { path = "../../trie-db", default-features = false, version = "0.28.0" }
