What is the current behavior?

Currently, supported version spits out the matrix of ALL currently supported versions of Magento by Adobe. One may not always want to support that wide of a matrix.

Fixes: #15

What is the new behavior?

We now offer custom and latest in order to allow users to more precisely define what they want.
