Support HTTP 1.1 Chunked transfer

Fixes #7929

@Oldiesmann Test and confirm

Something else seems to be broken with scheduled tasks now unfortunately. If I choose to run the task now, it says it was successful but the "next due" never changes and nothing is updated in the task log. I also have several tasks with "next due" dates in the past, and nothing has been updated in the task log in a while.

I suspect there is another issue then. The data is updating correctly at least though? That is the focus on this PR, which is to correct the data not being handled properly due to chunking in HTTP 1.1.

I do get a error when I run it myself still, but its due to a missing Use statement. I fixed that in: https://github.com/SimpleMachines/SMF/pull/7927/files#diff-0110925af7e28153225ee796276bc6329a889f3631c500c05527ad06a756b223

Tried it locally on my test board on Windows and it worked fine (your fix fixed the issue). Not sure why scheduled tasks aren't working on my server.

Already mentioned this in Discord but will post here as well for anyone who didn't see that. The issue with tasks not getting run on my board was because the Tasks directory was never renamed. I deleted the "tasks" directory, uploaded the one from my local copy ("Tasks" with a capital T) and updated the path in Settings.php and everything is working now. The change in this PR also fixes the issue with the latest-news.js file.
