Mnemosyne sync server container

Note: the image is quite large since mnemosyne (by default) requires much of Qt5 including the graphics stack.

Usage:

• Start with podman-compose up
• Generate a password, eg. echo 'password' | argon2 saltsalt -e
• Once started, add the following to the config.py file in the data volume:

remote_access_username = "user"
remote_access_password = "passwordhash"
remote_access_password_algo = "argon2"

• Restart the container
