Allow passing in further parameters when monitoring a given stop

[BenReim]

Currently only dvb.monitor() is exposed through the API. However, it's method signature only allows to specify the stopID , offset and amount parameter. I'm currently looking for a way to only monitor a stop with a given set of mode types, e.g. such as modeTypes = [tram, bus].

I would be willing to create a PR for such a method implementation, but wanted to get feedback ahead of time on such a new api method signature should look like?
