Make small and large cities data structure consistent

[decembrya]

Large cities parse expects to have "Incidență" in the json

covid-19-date-la-zi/utils/parse.js

Line 77 in c194afd

incidenta: parseFloat(city['Incidență']),

while small cities parse expects "Incidența"

covid-19-date-la-zi/utils/parse.js

Line 56 in c194afd

incidenta: parseFloat(city['Incidența']),

This can cause issues since the data automatically only creates jsons with "Incidența" for both sets of data. Propose to have them both use the same version and sanitize data to that version
