v0.2.7

# What's changed
### New features
- Now if you used the `wait_selector` argument with `StealthyFetcher` and `PlayWrightFetcher` classes, Scrapling will wait again for the JS to fully load and execute like normal. If you used the `network_idle` argument, Scrapling will wait for it again too after waiting for all of that. If the states are all fulfilled then no waiting happens, of course.
- Now you can enable and disable ads on `StealthyFetcher` with the `disable_ads` argument. This is enabled by default and it installs the `ublock origin` addon.
- Now you can set the locale used by `PlayWrightFetcher` with the `locale` argument. The default value is still `en-US`.
- Now the basic requests done through `Fetcher` can accept proxies in this format `http://username:password@localhost:8030`.
- The stealth mode improved a bit for `PlayWrightFetcher`.


### Bugs Squashed/Improvements
1. Now enabling proxies on the `PlayWrightFetcher` class is not tied to the `stealth` mode being on or off (Thanks to [@AbdullahY36](https://github.com/AbdullahY36) for pointing that out)
2. Now the `ResponseEncoding` tests if the encoding returned from the response can be used with the page or not. If the returned encoding triggered an error, Scrapling defaults to `utf-8`
