### Bug description
<table>
<tr><th>BEFORE</th><th>AFTER</th></tr>
<tr><td width="50%">Animation looks good if and only if the animated
square has no positive velocity (velocity towards center of screen). In
other case it moves much too fast and clamp to the opposite position
with no bounces</td><td>If square has some positive velocity it moves
visibly faster. Square always bounces when approaching clamp limit (with
rubber band effect on).</td></tr>

### Description of code change

I've removed a condition updating the derivative only when square is
within predefined boundaries - since we want to keep its springified
movement even if it is overshooting. Especially that we used to end
animation almost immediately after exceeding limits.

Since after this change the `derivative` is always modified we should no
longer compare it to zero, but use some epsilon instead.

## Test plan

I've tested it on this example:
https://github.com/MatiPl01/reanimated-issues, linked in the issue.
