rABCadd063177a26: [ecashaddrjs] Add function to support conversion to legacy format
Summary

T3096

Going forward, we will use utxo-lib and bitcoinjs-message for javascript applications that create transactions and sign / verify msgs.

These libraries are robust and well maintained. However, they require address input format to be legacy.

Include a toLegacy function in ecashaddrjs to support future implementation of above libraries.

Test Plan

npm test

It would be more robust to check isTestnet as !isMainnet. E.g. ecregtest prefix are testnet wrt cash address format.
Also we tend to add test nets over time but not main nets.

Improve check for mainnet or testnet

var VALID_PREFIXES = [
    'ecash',
    'bitcoincash',
    'simpleledger',
    'etoken',
    'ectest',
    'bchtest',
    'bchreg',
];

E.g. ecregtest prefix are testnet wrt cash address format.

Is this a prefix that should be added to VALID_PREFIXES ?

is bchreg a testnet address?

ecregtest and bchreg are both used for regression testing, so not a live chain. Supporting them depends on how you plan to use the lib, but I think you should have none or both. Both are testnet addresses as per address encoding.
