Add TypeScript support with ts folder

[Tomkoooo]

Had some issue using the package on ts based projekt so I added typesafety with creating all classes in ts.
Also published szamlazz.ts with the compiled version on npm so it can be used as now.

Thank you for your effort but I don't plan to convert the project to typescript. The type definitions are more than welcome.

Thanks for the reply.
I hope its not bothering that I re-released the package with typescript base under the name of szamlazz.ts.
But if you need I can fork the type definitions so whose in need can use the stable package with correct typescript support.

Should I do an index.d.ts file with ever type declaration in one place or one file for every class e.g. buyer.d.ts, invoice.d.ts etc.

Absolutely not. Feel free to fork and reorganise.

I will add the type definitions today or tomorrow because it is the most wanted feature request. Less effort from me if I do it.
