TS improvement to support longer ranges

[dmitriz]

#Issue
The current limitation of a 70 days range does not reflect a limit that is ideal for research of the evolution of NPIs, being more adequate for a casual look.

#Posssible solution
Two scenarios are possible:

• Find a way to make the default TS contain more entries by default on Desktop, leaving Mobile as-is.
• Develop a solution to allow the user to set whatever range they want, which would work both for Dektop and Mobile.
