If connection failed lib throws Faraday::ConnectionFailed exception

[qelphybox]

Bug
If connection failed lib throws Faraday::ConnectionFailed exception. You have to rescue from Faraday::Error which is quite unobvious

To Reproduce
Steps to reproduce the behavior:

1. Disconnect from iternet, make imposible to send request
2. Run

begin
  Zerobounce.valid?('[email protected]')
rescue Zerobounce::Error
  puts 'catch'
end
# >> Faraday::ConnectionFailed: Failed to open TCP connection to api.zerobounce.net:443 (getaddrinfo: Temporary failure in name resolution)

Expected behavior
Zerobounce::ConnectionError Failed to open TCP connection to api.zerobounce.net:443 (getaddrinfo: Temporary failure in name resolution)

[afrase]

I looked into this but it would require wrapping the #get call in a rescue and some refactoring of the base error class.
When ever I get some time I'll try to get this refactored to catch errors raised by faraday.
