Improve tag selector swipe-up handling

Maybe just motion speed thresholds should be adjusted, but it won't hurt to overhaul the whole gesture handling.
* It should be possible to maximize selector with one quick single-handed motion
* If a user drags the bar in one direction and then switches into other, swipe-up still had to be recognized
* It should be possible to place the bar into any position on the screen (any portion of the screen: 20%, 30%, 50%, 75% etc.)

This issue is continuation of https://github.com/ARK-Builders/ark-components-android/issues/21

Videos of how does it work right now:

Start by reading the tag selector gesture-handling implementation and the continuation issue linked in the description, then compare the two attached videos with the current behavior. Done means a quick single-handed swipe can maximize the selector, direction changes still recognize swipe-up, and the bar can be placed at arbitrary screen positions.
