Add data for Chisinau

[hiddener]

https://tranzy.ai/opendata is the official source for RTEC&PUA (trolleybuses & buses) Chisinau, Moldova. They give API keys. Docs: https://api.tranzy.ai/v1/opendata/docs

Did you find any way to get a complete GTFS zip file there? The individual files as json are a very impractical way to publish the data, as you first need to convert that back to csv and zip it before it can be used.

And I also can't find any source for the GTFS calendar.txt in the API documentation.

@jbruechert I've just contacted tranzy regarding the zip file. Will be back with updates if any.

Thanks!
