added preventDefault prop

[filkalny-thimble]

Fixes issue #221 by allowing user to call preventDefault manually within event handlers instead of having it always called for them.

Closing this PR as stale. While this preventDefault prop received an approval, the PR has been open since 2021 without being merged. If this feature is still desired, please open a fresh PR against the current codebase (React 19 compatible). Thank you for the contribution!

Reopening - this is a commonly requested feature for mobile touch scrolling.

Closing - Already Implemented!

This feature is already implemented in the current codebase as allowMobileScroll prop. See:

• Line 92-93 in DraggableCore.js: allowMobileScroll: PropTypes.bool
• Line 314: if (e.type === 'touchstart' && !this.props.allowMobileScroll) e.preventDefault();

Usage is functionally equivalent (just inverted logic):

// Your proposed API:
<Draggable preventDefault={false}>
// Current API (same effect):
<Draggable allowMobileScroll={true}>

Thank you for the contribution - your idea made it into the library!
