Correct import for sqlalchemy.pool.StaticPool

[bendichter]

I found this error with:

$ linkml-sqldb dump --help

Traceback (most recent call last):
  File "/Users/bendichter/opt/miniconda3/bin/linkml-sqldb", line 5, in <module>
    from linkml.utils.sqlutils import main
  File "/Users/bendichter/opt/miniconda3/lib/python3.9/site-packages/linkml/utils/sqlutils.py", line 21, in <module>
    from sqlalchemy import StaticPool, create_engine
ImportError: cannot import name 'StaticPool' from 'sqlalchemy' (/Users/bendichter/opt/miniconda3/lib/python3.9/site-packages/sqlalchemy/__init__.py)

It looks like the import pattern can be corrected. from sqlalchemy.pool import StaticPool works for me. I'm not sure why I am getting this error and it hasn't come up before. I have sqlalchemy 1.4.46 installed

Very odd. Our unit tests only test sqla2, but I am pretty sure the original code worked when we are all on 1.4.x! Anyway, better to work on a broad range of versions
