Sanitize version num from string to int by removing non-numeric characters

[kenlhlui]

I came across an issue when I was trying to initialize the Dataverse instance for borealisdata.ca (also (https://demo.borealisdata.ca/).

When I try to run this code:

from easyDataverse import Dataverse
dataverse = Dataverse("https://borealisdata.ca/")

The error message:

/dataverse.py:140, in Dataverse._connect(self)
    115 def _connect(self) -> None:
    116     """Connects to a Dataverse installation and adds all metadtablocks as classes.
...
--> 231 if int(major) >= 6:
    232     return True
    233 elif int(major) >= 5 and int(minor) >= 13:

ValueError: invalid literal for int() with base 10: 'v6'

The reason is that there is a leading v for the major version number in Borealis:
{"status":"OK","data":{"version":"v6.4.1-SP","build":null}}

This PR sanitizes the version number, ensuring the number can be changed from str to int, and can then perform the check.

Not sure this can be accepted! Because it's likely more a signle Dataverse instance issue!

@kenlhlui, thank you very much for the PR! I was completely unaware of this, and it’s great to have it checked. If you don’t mind, I’ve added a couple of tests and an additional check to your Dataverse instance.

It looks great! Sorry, I should have written the test as well. Thanks so much!

No worries, the most important thing is that you’ve spotted and fixed it! Merging 🙌
