Supported formats, networks and address types.
var Format = bchaddr.Format; // Legacy, Bitpay or Cashaddr.
var Network = bchaddr.Network; // Mainnet or Testnet.
var Type = bchaddr.Type; // P2PKH or P2SH.Test if a string is a valid Bitcoin Cash address of any type, in any format.
var isValidAddress = bchaddr.isValidAddress;
isValidAddress(null) // false
isValidAddress('') // false
isValidAddress('some invalid address') // false
isValidAddress('bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq') // false

Other functions in this library will throw an InvalidAddressError on invalid inputs.
