@Sean-Der I made this draft push to show the state before i start making necessary additions and other iterations

@jech Could you also be a reviewer to this.

[jech]

You've removed the tests? I don't agree, I think you should leave the tests. That way, when we adjust the tests, we know exactly how much the behaviour of the samplebuilder has changed, and we can decide whether the changes are acceptable or whether we should tweak the new samplebuilder.

[jech]

@midepeter why is this being committed with you as the author? Since I am the author of the code, I would expect to be credited. Please use the --author flag to the git command to properly credit me as the author.

[midepeter]

@jech oh, I will do that

sorry about that. This literally my first time in the open source space

I will do that. Apologies

Hey, I gave this a go and found two issues:

1. You've removed some functionality like WithMaxTimeDelay but the options silently apply. I'm assuming this is what you meant when you said "to show the state before i start making necessary additions and other iterations"
2. If the first few packets sent are padding packets, then no packets are processed until the padding packets end up being dropped when maxLate is hit.

Replaced with #2679
