Properly display affiliation strings in I/F

[aaccomazzi]

The aff field contains HTML-encoded text, and therefore should be displayed as such. At the moment, the interface escapes existing entities unnecessarily.

Example: https://ui.adsabs.harvard.edu/abs/2020AJ....160...68W/abstract

The affiliation fields looks like: Center for Astrophysics ∣ Harvard & Smithsonian, 60 Garden St., Cambridge MA 02138, USA
