Can't serialize with trie.T as property is private

[Bishoy]

I might be wrong but since T is a private property of CompactPrefixTree, I'm not sure how the sample would work serializing JSON.stringify(trie.T) and then retrieving the trie back . I would suggest instead something along the lines of :

const items = [
  "http://www.example.com/foo/",
  "https://www.example.com/baz/",
];
const trie = new CompactPrefixTree(items);
const serialized = JSON.stringify(trie);
 
// to deserialize
const trie2 = Object.assign(new CompactPrefixTree(),JSON.parse(serialized))

You're right on T being private. I probably ignored TS errors when writing that example.

I think it would be better to add a toJSON() method to CompactPrefixTree as well as a static fromJSON(json) constructor. Interested in sending a PR?
