requirements.txt already specifies a newer version, and the one currently used is causing problems

...which will prevent the whole thing with subscribestar post bricks displaying as they do

* add common "NekoImporter" class
* added/changes some docstrings
* apparently curlcffi just doesn't include failed response in error, so refactor
* ensure connections are closed at the end of transactions
* allow ratings to be set at downloadmanager post write
* disable blue nudge bubbles in driverless/chrome scraper
* ensure reloads wait for page load when adding cookies
* remove encryption and autoimport libraries for now

* prevent postlib/artistlib functions from rolling back changes by not closing the cursor
* not obtainable errors are now logged in debug level so it doesn't shit up sentry
* fix error caused when importerlib download method is used on posts that have duplicates

try to keep the transaction free of potential random locks on similar/duplicate image select by terminating it before attempting a write of the post data
