Support baseline alignment

[damianw]

TextViews are often baseline-aligned to other views. TickerView should also support layout_alignBaseline and other similar layout attributes.

Hi

Is there any plans to add res-auto:layout_constraintBaseline_toBaselineOf support to the library?

ConstraintLayout support layout_constraintBaseline_toBaselineOf,override getBaseline in tickerVIew class.
@Override public int getBaseline() { return (int) metrics.getCharBaseline(); }
