btrfs requires separate boot partition

Basic info:

Anarchy version:
February 2020
Installation method (VM/Host):
VM

What you expected would happen

No need for separate /boot partition, when using btrfs on root partition

This message is displayed by the installer:
Error: a separate /boot partition must be set up

Latest grub has support for btrfs on root partition, so this error message and separate boot partition are no longer necessary.
It would be nice if in the installer we could choose mount options for btrfs (such as compression).
