[Taproot] Add an utility for sorting leafs in order of weight (likelihood of use)

[motorina0]

It should not be required to sort in any sort of order, but we should offer some sort of helper function to help out.

Input:

• an ordered list of scripts with weights attached

Output

• a binary tree were the weights of the script are correlated with the length of the path from the tree root to that script leaf

Hi @motorina0, I’m interested in working on this issue.
Is anyone else already working on it? If not, can I take it? Do you have any suggestions or tips on how to approach it?

Bticoinops' Schnorr taproot workshop has a notebook on using Huffman constructor to achieve this.

• such functionality would be useful, but I'm not sure it should be part of this lib
• if you create an utility we can point to it in the readme

@motorina0 What did you have in mind for this issue? The huffman constructor does what I think this issue is requesting for.
