httr2 1.0.4

• req_body_file() now works with files >64kb once more (#524) and no longer leaks a connection if the response doesn't complete succesfully (#534).
• req_body_*() now give informative error if you attempt to change the body type (#451).
• req_cache() now re-caches the response if the body is hasn't been modified but the headers have changed (#442). It also works better when req_perform() sets a path (#442).
• New req_cookie_set() allows you to set client side cookies (#369).
• req_perform() no longer displays a progress bar when sleeping during tests. You can override this behaviour by setting the option httr2_progress.
• req_perform_iterative() is no longer experimental.
• New req_perform_connection() for working with streaming data. Unlike req_perform_stream() which uses callbacks, req_perform_connection() returns a regular response object with a connection as the body. Unlike req_perform_stream() it supports req_retry() (with @jcheng5, #519).
• req_retry() no longer treates low-level HTTP failures the same way as transient errors by default. You can return to the previous behaviour with retry_on_error = TRUE.
• resp_body_html() and resp_body_xml() now work when req_perform() is given a path (#448).
• New resp_stream_bytes(), resp_stream_lines(), and resp_stream_sse() for streaming chunk from a connection response (#519).
