change from pytoml to toml

The pytoml project is no longer being actively maintained. Consider using the toml package instead.

I came across this program as I was trying to package some python programs for voidlinux. I wanted to package this program so that packaging other programs would be easier. However, I found that pytoml was not in the void repositories and pytoml was deprecated. It would be helpful if a new release of this program could be made with the pytoml dependancy removed so I can add it to void's repos.

Oh, pytoml is deprecated. That's a shame, I thought it was the superior library compared to toml (the latter's output is a little more ugly).

This change caused a test failure but I've fixed that and released v1.5 to PyPI with the change.

@wimglenn thank you!
