feat: add one snap point change per one swipe

[IslamRustamov]

Motivation

Application I'm working on has a bottom sheet with 3 snap points.

Recently I was informed that there is an issue with it:

1. Bottom sheet is at the last snap point;
2. User quickly swiped a little bit;
3. Bottom sheet goes from last snap point to first one, ignoring the middle snap point.

So I was tasked to solve this by allowing user only one snap point change per swipe, but the library doesn't support this feature.

Here's the example of the problem:

We can see that most of the time, a little swipe is causing our bottom sheet to skip the middle snap point.

Here's the example of how it works with my changes:

We can see that now I can't skip the middle snap point and am forced to do one more swipe to get to the next snap point.

after I synced my fork - some problems jumped out, going to put in draft until I fix them

It stopped working the right way after these detents

the only problem that left is that animation is instant in case if I overdrag, will look into that but will be glad for help

upd: nervermind, this problem is existing in master, not the problem caused by my changes
