tweak(client/streaming): rewrite

Was going to split into separate imports, then
remembered why I didn't in the first place.
Improved annotations.
Changed timeout into a for loop, and increase default to 500 ticks.
Less variable reassignments.
Allow functions to be called outside threads, but will not check if the
request was successful (has loaded).
