fix: relax pandas version requirements for databuilder

[henridwyer]

Summary of Changes

Relax the pandas version requirements for the databuilder package, which is currently limited to a version released over 2 year ago, to allow for more recent versions. This will make it possible to easily include the package in repos that use modern versions of pandas.

Tests

Tested on pandas 1.4.2 (the current version).

Pandas usage was already tested in unit tests so no new tests are necessary.

Documentation

Very little of the pandas API is used, essentially just read_csv, which is a very stable part of the API.

Very little of the pandas API is used, essentially just read_csv, which is a very stable part of the API.

You raise a very good point, which begs the question couldn't this part be refactored to use the csv.reader, which is a standard module in python?

There is a unit test error, which seems to be related to fastapi imports:

/opt/hostedtoolcache/Python/3.7.13/x64/lib/python3.7/site-packages/starlette/concurrency.py:10: in <module>
    from typing_extensions import ParamSpec
E   ImportError: cannot import name 'ParamSpec' from 'typing_extensions' (/opt/hostedtoolcache/Python/3.7.13/x64/lib/python3.7/site-packages/typing_extensions.py)

I saw it in other builds such as https://github.com/amundsen-io/amundsen/runs/6338504223, so I suspect it's not related

@feng-tao This is a unit test import error that does not relate to our change. Any way we could get past it or get our PR merged?

[henridwyer]

I saw a fix for the fastapi bug was merged. So I rebased this branch @feng-tao

[feng-tao]

thanks @henridwyer
