Saveas doesn't support pdf

[MRedies]

The plotdos routine:
https://masci-tools.readthedocs.io/en/latest/module_guide/code.html?highlight=plot_dos#masci_tools.vis.plot_methods.plot_dos

has a saveas argument, which I call with saveas="bla.pdf". This results in a file called bla.pdf.png. This is a bit unfortunate, since often you want a pdf, rather than a png (it's a vector graphic).

The saveas option only takes the filename without extension (however we could change that if it is wanted, overrriding the format if it is included in the saveas argument). To specify the format you can pass the keyword argument save_format with the wanted format, i.e. 'pdf' (You can also pass a list of formats if you need multiple different ones). Note that you can also specify additional options for saving with the save_options argument

You can find the information in the table

Ok then I was confused by the interface. In matplotlib they determine the type trough the name, but I think either way is fine.
