Add the conda env file for python2 dev environment

[abhi18av]

Hi @bebatut,

First off, thanks for this package!

I was trying to find an automation tool for interacting with the ENA website and found this library. For now, I've created an environment_py2.yml via conda env for a consistent development environment.

It includes all the packages and the their dependencies.

I think the reason for failure for this test is simply because the ENA database has more data now. Please let me know if this assumption is correct and I'd update this test.

Regarding the tests, here is the status.

This environment file might also help us to update the testing mechanism on TravisCI since right now it is failing due to incompatible versions of Sphinx package

Hi @abhi18av,

Thanks a lot for your pull request and for using this tool 😄

I just got a baby so I do not know when I will have time to have a look at it.

For the tests, you are probably right. They may need to be updated given changes on ENA. If you have some times to look at them, it would be awesome

Hey @bebatut , first off congratulations 👶 👨‍👩‍👧 !

I completely understand about the priorities right now, no hurry here.

Just wanted to tell you that I'd probably be upgrading the tool to be installable in python3 conda environment and will be creating that PR soon.
