httr2 1.0.2

• req_body_file() now only opens a connection when the request actually needs data. In particular, this makes it work better with req_perform_parallel() (#487).
• req_cache() no longer fails if the rds files are somehow corrupted and now defaults the debug argument to the httr2_cache_debug option to make it easier to debug caching buried in other people's code (#486).
• req_oauth_password() now only asks for your password once (#498).
• req_perform_parallel() now works correctly with req_cache() (#447) and now works when downloading 0 byte files (#478)
• req_perform_stream() no longer applies the callback to unsuccessful
  responses, instead creating a regular response. It also now sets last_request() and last_response() (#479).
• req_url_query() now allows you to opt out of escaping for multi-value parameters (#404).
