Flower fix

A resource pack that fixes block models so that they flip correctly when viewed from the back.

Example of the issue:

• Looking south !Vanilla cornflower looking south
• Looking north !Vanilla cornflower looking north

With flower fix, this issue no longer occurs

This should be compatible with most other resource packs, I would recommend giving them higher priority. On pre 1.20.2 versions, you can ignore the "made for a newer version of minecraft" warning.
