fixed y value for HMSegmentedControlTypes

Fixed y value for `HMSegmentedControlType` of `HMSegmentedControlTypeTextImages` and `HMSegmentedControlTypeImages` so that it is a function of the the value of `HMSegmentedControlSelectionIndicatorLocation`.

example:
Prior to this, if you increase the value of `selectionIndicatorHeight` when `HMSegmentedControlSelectionIndicatorLocation == HMSegmentedControlSelectionIndicatorLocationDown`
and
`HMSegmentedControlType == HMSegmentedControlTypeImages`
 then the image floats down as the indicator grows and they will overlap. My previous pull request that you accepted already fixed this for when `HMSegmentedControlType == HMSegmentedControlTypeText`
