New language request: tzl/Talossan

As the language has an ISO 639-3 code, support will be added here for it at some point. Reading the Wikipedia page about it, I'm not keeping my hopes up that this language will ever go further than an ultra niche. My personal opinion is that skilled wiki editor time can be spent a lot better than with working on this, but everyone with time to spare in a free country, can choose to spend it the way they want.
