Do not log progress bar to stderr

[stellarhoof]

Our application emails devs when some program logs to stderr. Right now I can override pyppeteer's root logger to my needs. However https://github.com/stellarhoof/pyppeteer/blob/dev/pyppeteer/chromium_downloader.py#L85 uses stderr by default. Could we customize this? At the very least we could try and reuse the first stream handler that the logger at https://github.com/stellarhoof/pyppeteer/blob/dev/pyppeteer/chromium_downloader.py#L19 has. That way customizations that clients of your library do to your logger carry over.
What do you think?

I've just taken a look at the source of tqdm, it's hard coded and no option to control this behavior.
If you don't need log on installation process, how about separating installation and your script like:

pyppeteer-install 1>/dev/null 2>&1
python your-script.py

[stellarhoof]

I think you can pass it a file argument
(https://github.com/tqdm/tqdm/blob/master/tqdm/_tqdm.py#L647). The default is stderr (https://github.com/tqdm/tqdm/blob/master/tqdm/_tqdm.py#L751)

Unfortunately your suggestion doesn't completely solve the problem since I cannot change how our scripts are run. Additionally, the download process gets triggered often (which I have to investigate) so installing at the beginning will not stop the other downloads (we run the scripts periodically)

Do you want to record progress bar to a log file?

Adding option to launch function may solve this issue, but I'm sorry but I don't implement for this as I think your requirement is so specific on your use case.
PRs are welcome.

Ok I will make a proof of concept PR and you decide.

Actually it might be better to make an issue upstream to tqdm.
