Add segment duration getter

[rismirnov]

Overview

I suggest adding a getter to get the duration of a given segment [startFrame, endFrame].

const player = new DotLottie({ segment: [0, 100], /* other params */ })
const frameRate = player.totalFrames / player.duration;
const segmentDuration = 1000 * (player.segment[1] - player.segment[0] + 1) / frameRate;

Type

• New feature

Motivation

I needed to determine how much time remained before the segment would finish playing after some time

Labels

• Add the Type: Feature Request label to this issue.

Thanks @rismirnov
I think this is a good addition. Just one note from my side: to minimize the impact on the bundle size, we can add this as a utility function that we export from our dotlottie-web package for optional use. Adding it directly to the DotLottie class would unnecessarily increase the bundle size, as this is not a very common use case.
