When I try to set lxml==4.9.1 , it fails:

RROR: Cannot install -r /app/list.txt (line 97) and lxml==4.9.1 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested lxml==4.9.1
    pyiso 0.4.0 depends on lxml==3.6.4

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

@ajdonnison Would you be able to provide the Python version (and ideally lxml and pandas versions) you're working with, as it seems like a lot of people are having installation issues?

By removing the pandas version constraint in the source code, I was able to get a conflict-free install via setup.py on Python 3.10.0 by resolving other dependencies using conda. I haven't yet run through the full test suites to see what breaks in pandas 0.21 let alone 1.x. It looks like the tests also have a number of dependencies (nose, parameterized, mock, libfaketime, requests_mock, freezegun) which are not included in requirements.txt or setup.py.

When I try to install pandas==0.20.3 to satisfy the pandas version constraint, I get the error pandas==0.20.3 -> python[version='>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0']

However, I was running into some lxml errors which indicated issues with a python version below 3.8.5. My suspicion is that @ajdonnison is working on a version without the pandas constraint, or has a lucky python+lxml+pandas combination that the dependency solver can't figure out...

Thanks @ajdonnison for your work on this; I last touched the code in 2017(!) but am now back and looking at EU data, for which I'm hoping your code will be helpful!
