Add barrier-free information for buildings

[octycs]

Is your feature request related to a problem? Please describe. Not all of the older TUM buildings are barrier-free. We should add information about this, and who to contact.

Describe the solution you'd like Provide a small info section on building pages with information. This could include information about accessible entrances and contact persons (the TUM Campus App has already data on this). If there are official pages with information, we could link them as well.

Describe alternatives you've considered Feel free to propose alternatives.

Additional context Information by TUM and additional data collected on wheelmap.org.

Tasks could include:

• Collect general and per-building barrier-free information. The building information could be added e.g. to data/sources/01_areas-extended.yaml and the general information page in the HTML (see below)
• Add a new section specification in sections: in data/data_format_geo-entry.yaml and implement it in e.g. a new section-generating step after -- 81 Generate overview sections
• Implement the display HTML/CSS in webclient/src/views/view/view-view.inc|.scss
