#84 Fixes of Schools are not plotted in map in streamlit app (#90)

* Fixes of Schools are not plotted in map in streamlit app

* Fetch Schools Latitude,Logitude from session rather than fetching data from given school's sample_data

* Use School List instead of fetching lat,long,scode from school-center-distance and use dataframe in tab3 instead of re-reading from tsv file
