Getting "NameError: name 'ir' is not defined" in octopus_energy/__init__.py line 91

Describe the bug

Since updating to the newest version 6.3.1 via HACS, the Octopus Energy integration is not starting. All sensors are reporting "this entity is no longer being provided".

It seems that the integration is erroring on startup. The relevant log entry is below.

My guess is that commit 1198034, committed just before the 6.3.1 release, may be responsible.

To Reproduce

Upgrade to 6.3.1 and restart HomeAssistant.

Expected behavior

The integration to provide sensors with data.

Home Assistant Version

2023.3.6

Integration Version

6.3.1

Fresh Install?

Upgrade using HACS from 6.0.0 to 6.3.1

Sorry, this was caused by a silly mistake by myself that wasn't caused by my CI. I'm planning on adding some additional checks to ensure this doesn't happen again. A new release (https://github.com/BottlecapDave/HomeAssistant-OctopusEnergy/releases/tag/v6.3.2) should rectify this.
