Live stream DVR not working when target latency is set

[hernanrz]

If you set options to manage playback latency, then DVR doesn't work as expected when a user clicks on the bar, it instantly goes back to the rightmost part of the bar.

You can see this behavior on the demo page https://demo.ovenplayer.com/#%7B%22playerOption%22%3A%7B%22autoStart%22%3Atrue%2C%22autoFallback%22%3Atrue%2C%22mute%22%3Atrue%2C%22sources%22%3A%5B%7B%22type%22%3A%22ll-hls%22%2C%22file%22%3A%22https%3A%2F%2Fllhls-demo.ovenmediaengine.com%2Fapp%2Fstream%2Fllhls.m3u8%22%7D%5D%2C%22hlsConfig%22%3A%7B%22liveSyncDuration%22%3A1.5%2C%22liveMaxLatencyDuration%22%3A3%2C%22maxLiveSyncPlaybackRate%22%3A1.5%7D%7D%2C%22demoOption%22%3A%7B%22autoReload%22%3Atrue%2C%22autoReloadInterval%22%3A2000%7D%7D

If target latency is set, hls.js will always try to set playback time to (latest - target latency). I think we need to check how it can be applied together when it is a DVR.

Perhaps if the DVR seek bar is clicked/moved target latency is disabled, and if the "live" text is clicked to seek to the head of the stream, or the seek bar is dragged all the way to the right, you re enable target latency?

It looks like I can dynamically change the target latency setting.
