Bech32 addresses for testnet and mainnet

[mbnissen]

https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki

As stated here bech32 address uses "bc" for mainnet and "tb" for testnet.

This library marks both to be valid in both testnet and mainnet

Yes, I faced the same problem

That's because of

wallet-address-validator/src/crypto/segwit_addr.js

Lines 73 to 88 in bcd0c8f

	function isValidAddress(address, hrp) {
	var hrp = hrp || 'bc';
	var ret = decode(hrp, address);
	if (ret === null) {
	hrp = 'tb';
	ret = decode(hrp, address);
	}
	if (ret === null) {
	return false;
	}
	var recreate = encode(hrp, ret.version, ret.program);
	return recreate === address.toLowerCase();
	}

which tries both prefixes, bc and tb.

Also, I think we should check address prefix before making any further calculations.

#70 seems to fix this.
