Add Citymapper parser

[Funeoz]

This PR introduces initial support for the transportation app Citymapper.

It generates custom HTML reports with interactive Folium maps for:

• Location history with chronological markers
• Saved trips (home/work markers and lines between locations)
• App/user preferences (device info, last location, session data)

@Funeoz do you have test data or report screenshots you can share?

@Funeoz this looks really cool, I'm assuming Folium is a third party library? If so we'll need to add it to the requirements.txt file

@stark4n6 It's already in the requirements.txt file. That's why I used it😉

@Funeoz I wasn't even aware, I suppose I should have looked first, this looks fine, will merge shortly
