[Slider] Tick size changeable

[neclomant]

Is your feature request related to a problem? Please describe.
I want to do slider with ticks that have size bigger than default.

Describe the solution you'd like
I suggest it may be a property like tickRadius or tickSize. Also there is need to enable isAntiAlias flag to tick paint if tick size will be large

Describe alternatives you've considered
Now I do this dirty through the reflection

val cls = Class.forName("com.google.android.material.slider.BaseSlider")
cls.getDeclaredField("activeTicksPaint").apply {
            isAccessible = true
            (get(mySlider) as Paint).apply {
                isAntiAlias = false
                strokeWidth = desiredSize
            }
            isAccessible = false
        }
