feat: Add Danish voice

[HThuren]

I have translated the 2 voice files, but had no sucess in the actual text to voice with phyton and azure.
I hope you can do the actual creation, the right neural settings is supposed to be proper chosen.

Hi @pfeerick, do you have a possibility to try to merge this PR and run the generate of danish voices ?

[pfeerick]

Yup. At a glance, it looks fine, and it's generally better for me to do the generation anyway since then I foot the bill if it runs over ;)

[pfeerick]

Ok, you might need to re-save those CSV files... they need to be UTF-8 formatted/encoded, otherwise the "special symbols" won't come through properly.

[HThuren]

Right, i have made a conversion by ultraedit to uft8, but is it right looking ?

[pfeerick]

I'm on mobile atm, but from the github change view it seems right, getting the proper characters now instead of the nasty unknown diamond questionmark character. Next step will be to run the generator script in about an hour and see if it chokes again ;)

[HThuren]

Very god, thx

[pfeerick]

Right, so had to fix up some issues with the double quotes (yay, build-checks.py is earning it's keep!) and after that, they generated fine. I'll merge and trigger a release build and then you'll be able to get the final normalised zip file and see how they sound.

Thank you, great job by you, most ok, but created a new PR #54 for minor changes
