Added -best-by ping|speed: -best/-conf and both tables can now pick
the fastest endpoint instead of the lowest-latency one. -best-by speed
runs the speedtest phase by itself, even under -best/-conf -.
-conf-type mihomo-jsonwrites the same proxies as a JSON array- fix: mihomo wireguard proxies now use the
peers:list instead of
mihomo's legacy top-level syntax
