now, it will put files under BASE_DIR/STREAM/VARIANT/HOUR/FILE.ts
This brings downloader in line with restreamer's concept of base_dir
* Fix bug where soft timeout is not cancelled if an exception occurs
* Various logging tweaks
* Prevent master playlist wait time from going negative
* Stop gracefully if stream worker detects end of stream
* Don't treat master playlist 404 as an error, it just means the stream isn't up
* Set a reasonable log format
* Make soft timeouts not always fire
* Change soft_hard_timeout signature slightly for ease-of-use
* Make renames not fail if file already exists
* Misc typos
This makes the code crazy complicated and messy, but means we can be persistent about
not giving up, while still retrying at the same time, and trying multiple urls at once

See docstrings for a full discussion on some of the failures we're trying to work around.
This is a useful library and we might as well use it.
Copying it over and slightly modifying it to work was easier than importing all of streamlink.
