Adds ELO card type

This adds ELO bin ranges and ELO brand logic in general. ELO is in a
partnership with Discover and is part of the Discover Global Network.
Using the ELO BIN ranges before the Discover regex allows those cards
to be identified correctly.

It also adds `elo` as a supported cardtype for the Adyen gateway.
