Description

Updated httpx module to v0.25.0 and relative dependencies to their last github branch/tag versions

~atm not tested,~ tested on android "BlockingIOError" error raised with httpx version 0.23 (#1485) dont happens anymore but now httpcore.RemoteProtocolError: Server disconnected is raised always after some time, that prevent addon to working well (usually this error is raised after waiting few minutes or while/after watching a video)

httpcore.RemoteProtocolError: Server disconnected is a custom error of httpcore and there are no specifics info on how to fix/workaround this problem, testing Requests module seem dont raise similar problems
