Hyperlink Support

[97WaterPolo]

Adaptation of a previous version PR #352

I found the pull request for a previous version while seeing if native Hyperlink support was added. I personally don't need any other "formulas" just the HYPERLINK to have clickable cells to external websites. Not sure if this will be useful but it is just added the regex and xml from the above PR. First ever PR so not sure if I am doing this right, but a small change if anyone needs hyperlinks like me.

Hi @97WaterPolo !
Thanks for submitting your first PR. We try to have the same features for XLSX and ODS files. So I can't accept this PR as is (+ broken/missing tests). Anyway, I'll leave it open so that people can use what you did in their project/fork.

I think this feature also very good.
Can you describe @adrilo what still needs to be done so that this PR is accepted.
How must the hyperlink syntax look like that it fits?

Another possibility would be not only to set the cell values from outsite
Means other (xlsx, ods) xml elements.
