Next steps for Wed 2/15:

• extract X, Y, and yaw(?) values from limelight/botpose
• convert X and Y to inches, figure out if yaw needs to be converted (e.g., degrees to radians or vice versa)
• write converted values to
  • smart_dashboard(sp?)/botPoseX
  • smart_dashboard(sp?)/botPoseY
  • smart_dashboard(sp?)/botPoseYaw
• Also read the correct value from limelight/?? to determine whether the limelight has a valid tag or not

Update swerveometer so that
IF the limelight has a valid tag THEN it resets the bot's pose estimate (the x, y, rotation values the robot thinks it currently has) to the limelight values (note: if the limelight does NOT see a tag, the pose estimate should NOT be updated from vision--it would instead be updated by the swervometer's odometry)
