Add chart for guiding RMS vs time in addition to existing metrics/chart for image quality attributes (such as HFR, # of stars, ADU etc)

[ajaymandke]

I would like to request to add Guide chart (for last x min) in NINA web session manager in addition existing metrics chart.
This will allow to use NINA web manager as quick readonly dashboard for remote monitoring without having to RDP into imagine PC or change the existing chart back and forth to see the guiding information.

Thank you.
