dependency conflict

[k-ebu]

The sqlalchemy version dependency is different from docs and src.

docs:

Prerequisites
You will need the following softwares to run, build and test the dialect. Everything apart from Python and pip can be installed via pip itself.

• Python 3.x or higher
• pip 22 or higher
• SQLAlchemy > 1.3.24 and < 2.0
• vertica-python 1.1.1 or higher

src:

    install_requires=(
        'six >= 1.10.0',
        'sqlalchemy<2.0.0,>=1.4.0',
        'vertica-python>=1.1.1'
    ),

Is it must be higher than 1.4.0?
I would like to use this dialect for Superset, but apache-superset is not supported sqlalchemy 1.4.0 now.

if I install sqlalchemy==1.4.46:

apache-superset 2.0.1 requires sqlalchemy!=1.3.21,<1.4,>=1.3.16, but you have sqlalchemy 1.4.46 which is incompatible.

if I install sqlalchemy== 1.3.16:

vertica-sqlalchemy-dialect 0.0.1 depends on sqlalchemy<2.0.0 and >=1.4.0

I think that this issue is related to DataHub test failure. (datahub-project/datahub#7059)
Could you support the sqlalchemy version lower than 1.4?
