[BUG] Zilliqa::Util::Validator.address? false positives

[zhulik]

Zilliqa::Util::Validator.address? returns false positives for obviously invalid addresses.

address = "zil1aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
Zilliqa::Util::Validator.address?(address)

Expected result:
false

Actual result:
true

Seems like Zilliqa::Util::Validator.address? uses only regexps to validate the address and doesn't check if the argument is a valid bech32 address.

I found a workaround:

address = "zil1aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
Zilliqa::Util::Validator.address?(Zilliqa::Util::Bech32.from_bech32(address)) rescue false

this snippet returns false because Zilliqa::Util::Bech32.from_bech32(address) raises an error when invalid address is passed:

2.6.3 :006 > Zilliqa::Util::Bech32.from_bech32(address)
Traceback (most recent call last):
        2: from (irb):6
        1: from (irb):6:in `rescue in irb_binding'
NoMethodError (undefined method `[]' for nil:NilClass)

It might make sense to check if the argument of Zilliqa::Util::Validator.address? is a valid bech32 address. WDYT?
