Sqlalchemy 9.0 compatibility

[brodul]

Hi,

there is a new version of Sqlalchemy. I installed almir from pypi and I got the following error

(test)brodul@moon:~/test$ pserve production.ini

    from sqlalchemy.orm.util import _is_mapped_class
ImportError: cannot import name _is_mapped_class

The _is_mapped_class has been removed from the code.

I recommend others to use the script install or manual install as described in docs.
