temp dir not working on Windows

• Python version: 3.7

Description

The usage of a temporary directory does not work in Windows. The issue is that in many systems the temporary directory is expanded from the %temp% environment variable. This often contains a tilde character (e.g. C:\Users\ALEXAN~1\AppData\Local\Temp). Unfortunately neither pdflatex nor lualatex can deal with the tilde character unless special workarounds are used (https://tex.stackexchange.com/questions/425954/tilde-in-a-image-path).

For itikz the fix seems easy, it operates in a given working directory so the full path is not required. I will open an appropriate pull request.

Merged and updated to pypi for v0.1.5

Thanks again, @asteppke!
