Support xlink:actuate=“onRequest”

Is your feature request related to a problem? Please describe.
We are integrating with Ads, and would prefer to use DASH-IF's latest SGAI specifications that allows us to delay filling the Ad Pods while reusing the player heuristics to maintain Quality of Service. Please see: https://dashif.org/docs/CR-Ad-Insertion-r8.pdf and https://drive.google.com/file/d/1TwSuMGa1gfesdWBvlbK1rHLNVwiZNX3l/view for more information. I've asked questions out to the DASH-IF forum about impact to the player timeline (amongst others): Dash-Industry-Forum/AdInsertion#83

Describe the solution you'd like

• Support for xlinks "onRequest", and some handling to indicate whether a period being played is an Ad or not, and/or exposing manifest events so we can track it on our own
• Exposing Timed Metadata from the stream
• Support for Dash Patch Manifests for Live Streaming

Describe alternatives you've considered
We are using CSAI to workaround this limitation, but would prefer to use SGAI to capitalize on the player qos calculations to maintain qos on low bandwidth connections.

We may need to do something similar to handle HLS interstitial support. We will be investigating the work soon, but may take a while to implement. This will require major reworks to implement.

Hi, I was wondering if you could share anything about how the discussions with Zach Cava are progressing on this? We are hoping to capitalize on support for SGAI in early/mid 2022 in ShakaPlayer. Would that be a realistic expectation to have?

@ronak2121 I can see XLink on Request is not supported yet on Shaka Player
Then how you are going with SGAI ??
