Looks like people have been busy tonight.
- DM channel cache methods are now gone, as v8 does not give events pertaining to DM creation or deletion. Sending a DM to a new recipient will now require a create DM API call and a create message API call per the new layout.
- Fixed bug where you'd get KeyErrors on reconnects in the GUILD_CREATE_EVENT (thanks @FasterSpeeding for fixing that so quickly tonight).
hikari.utilities.date->hikari.utilities.time- Fixed incorrect conversions from timedelta types to JSON compatible types.
- Removed delete_integration REST endpoint, as it now just kicks the bot from the guild, which is what leave_guild already does anyway.
