   * Canonicalize a Bitcoin Cash address for a specific version
   *
   * Starting on January 14th, 2018 Bitcoin Cash's bitcoin-abc node switched over to using cashaddr
   * encoding for all of their addresses in order to distinguish them from Bitcoin Core's.
   * https://www.bitcoinabc.org/cashaddr. We're sticking with the old base58 format because
   * migrating over to the new format will be laborious, and we want to see how the space evolves
   *
   * @param address may or may not be prefixed with the network, example bitcoincash:pppkt7q2axpsm2cajyjtu6x8fsh6ywauzgxmsru962 or pppkt7q2axpsm2cajyjtu6x8fsh6ywauzgxmsru962
   * @param version the version of the desired address, 'base58' or 'cashaddr', defaulting to 'base58'
   * @returns {*} address string
