Fix isDriveAligned

[aidnem]

Purpose During Brawl, I flipped all of the aligns by 180 degrees to make it aim at the speaker (instead of shooting the note at the referee). However, I forgot to update the isDriveAligned function. This means that it would align correctly but then think that it wasn't aligned, causing us to never auto-shoot, and requiring all mashers to force shoot. According to Jack, this should only be done when on the red alliance.

Project Scope

• [ ] Add a conditional to flip target heading in both omega controller and isDriveAligned when on the red alliance (as per this comment)
• [ ] Verify that the alignment target heading for the omega controller is correct (not flipped 180 degrees)
• [ ] Verify that the alignment target heading in isDriveAligned is correct (not flipped 180 degrees)
• [ ] Test it in sim to make sure that isDriveAligned is returning true.
• [ ] Test it on robot (should be able to shoot in auto and in teleop without using force-shoot button).

@jkleiber I can't really fix this until we have the changes from BRB pushed, as the rewriting of how drive alignment works would render my solution obsolete if I made the changes on the current branch. The changes were never pushed after the competition but they're on comp/brb on the laptop hotel (if I remember correctly) so we should be good to go as soon as we get to shop tonight.

Fixed in #59.
