feat: added onSnapToItem trigger for didMount and update index changing logic

[karkengc]

Changes made is to fix below issue:

1. No onSnapToItem trigger for initially mounted carousel item
2. For when loop is true, the index changes when scrolling beyond 1 loop and back to index=0, the index is first changed to rawDataLength before resetting to 0, which will cause slight delay when updating pagination dots.

Hi @karkengc , don't know if you will find this useful but basically this is what I did this in order to fix the delay

using the exported fn onProgressChange I use the following handler

const handleProgressChange = (_: number, progress: number) => setCurrentIndex(Math.round(progress) % data.length);
