Update requirements.txt

[chrwm]

When cloning the repo and creating and environment for development purposes from requirements.txt, I stumbled upon requirement problems for pandas and sqlalchemy while testing code.

@jh-RLI is it fair to fix both package versions to pandas==1.2.4, sqlalchemy==1.3.16 as noted here or does anything speaks against it? If only the latter is possible then a dev note would be nice.

sure you can update this in the requirements.txt.
Maybe we should use a =< instead of == to make it less strict but thats not relevant for now. I will take another debug tour to finally fix the oedialect and remove this restriction next year :)

One thing I just noticed is that in the tutorial sqlalchemy==1.3.16 is specified and in setup.py (and actually installed when oem2orm is installed) sqlalchemy==1.3.14 is specified.
I am currently editing also the tutorial and could change it, if is wrong there.

I think 1.3.24 or .22 is the Last version That is supported. If you can confirm that then we shuld include it.

This issue remains and I just ran into it. Just to let you know ;)
Also, I believe it needs to be updated in the setup.py as well.
