Change session metadata (height & mass)

[nicos1993]

Hey all! I am trying to modify the height and mass metadata before reprocessing but I am running into a different issue. The framerate seems to be getting set to 60 Hz due to the if statement referencing existingMeta... but I believe it should be existingMeta['settings] - framerate exists inside there... as in my case the framerate is 120 Hz.

To change the session metadata I had to modify the settings_field variable and include 'mass_kg' and 'height_m'
