Library Enhancement - 8-pin control for 2x 4-pin Stepper Motors

[tuneersaha]

This pull request contains code that will enable the library to have 8-pin control which would translate for 2x 4-pin Stepper Motors to be able to work in tandem. This will help Arduino boards to run rovers in front-wheel or rear-wheel drive using stepper motors.
