Changes

- Respect limit for `get_trips()`: The `get_trips()` function now respects the specified limit.
- Removed debug: The debug parameter has been removed. Please use the logging module to set the desired log level instead.
- Renamed `obj` to `models`: Improved clarity by renaming the obj directory to models. You will need to adjust your imports.
- Added station enum: Introduced a station enum for better organization and readability. No more searching for your station identifier!
- Revised readme and examples: Updated the README file and examples for better understanding and usage.
- Using logging module instead of prints: Replaced print statements with the logging module for better logging practices.
- Update requirements.txt: Updated dependencies in requirements.txt to the latest versions.

Thanks to mhorst00 for this contribution in 54

If a trip is very short (<1minute) the VVS API appears to omit the duration property which resulted in an exception. This has been fixed.

Added more csv including station info.
Please refer to [this issue](https://github.com/FI18-Trainees/vvspy/issues/12#issuecomment-568175314) if you cannot find your station.
