v4.21

What's Changed

This version is a small bugfix version, that focuses on getting battery upgrades better for 2011-2012 ZE0 users. This version fixes the known issue #25 ! We achieve this by sending more proper CAN messages towards the battery, resulting in fewer active error codes. Massive thanks to @nzautomate for the CAN findings!

• Bugfix: ZE0 CAN sending improvements by @dalathegreat in #28
