Match all institutions in xlsx to entities from ZZZS API, getting a zzzsSt ID

[stefanb]

So that every record in csv/dict-institutions.csv gets a zzzsSt and all available data (website, phone....) from zzzs/institutions-by-category.csv.

Missing matches for:

• ZD LJUBLJANA - BEŽIGRAD ... ZD LJUBLJANA - ŠIŠKA
• OSNOVNO ZDRAVSTVO GORENJSKE, OE ZDRAVSTVENI DOM BLED ... OSNOVNO ZDRAVSTVO GORENJSKE, OE ZDRAVSTVENI DOM ŠKOFJA LOKA
• MDENT, ZOBOZDRAVSTVENE STORITVE, MIHAJLO FRANGOV S.P.

Regex for finding them in csv: ^[0-9]*,,
