v5.0.0

• Breaking: A lot of details regarding the metrics collection system have been reworked. (#160)
  • Switched from using the metrics crate to using the promtheus crate.
  • Usage of the new library and new config types now allows you to specify a Registry
    (from the prometheus crate) to register the metrics on, instead of being forced
    to use one global registry like with the metrics crate.
  • The config option metrics_identifier in the config has been replaced by a
    MetricsConfig enum, which now allows complete flexibility regarding what labels
    are added to the metrics. (Previously, only client => a_value_chosen_by_you could be
    added, and adding it was mandatory due to the API design I had chosen previously.)
  • This also means you can now specify any amount of additional key => value label pairs
    to be placed on the exported metrics. I imagine this to be useful to export any kind of
    metadata about your application/use-case.
  • The metrics have been renamed from twitch_irc_* to twitchirc_* to align with
    the prometheus naming conventions.
  • twitch_irc_reconnects has been renamed to twitchirc_connections_failed to better
    reflect what it actually counts.
  • Added twitchirc_connections_created as the obvious counterpart to aforementioned metric.
• Breaking: Handle emote_sets as Strings since not all of them are in fact u64s (#162)
• Breaking: Removed ChatClient::say_in_response and ChatClient::reply_to_privmsg in favour
  of a new API design (Chatclient::say_in_reply_to) which does the same thing as the previous
  functions, just with a sleeker API design. (#166)
• Breaking: Removed support for parsing HOSTTARGET messages (Twitch has removed Host mode since 2022-10-03) (#183)
• Minor: Added me and me_in_reply_to methods to send /me messages. (#170)
• Minor: Implement Clone for RefreshingLoginCredentials. (#176)
• Minor: Implement Eq for many structs. (#177)
