Make a left side 3 ball auto

[jcorcoran]

for when our alliance partner has a 3ball right side auto

Create a 3ball auto (4 if human player feeds us) that:

• starts out running our 2 ball auto
• Drives under the hangar and to the loading station ( to avoid colliding with our 3rd alliance partner who may be backing up for taxi)
• grabs the ball from the loading station then drives back and shoots from where we started
