Allow multiple FIP channels in plot axis of session scroller

[alexpiet]

Allows plotting multiple FIP channels in the same axis on the session scroller:

fip = [
    ["G_0","Iso_0"],
    ["G_0_dff-bright","Iso_0_dff-bright"],
    ["G_0_dff-bright_mc-iso-IRLS","Iso_0_dff-bright_mc-iso-IRLS"],

]
plot_session_scroller(nwb,fip=fip)

Can you specify what is needed to test this function? (e.g. preprocessing for nwb)
And can you also specify what is expected behavior?

This is what I did and the output:

 from aind_dynamic_foraging_data_utils.nwb_utils import load_nwb_from_filename
  import aind_dynamic_foraging_data_utils.nwb_utils as nwb_utils
  from aind_dynamic_foraging_basic_analysis.plot.plot_session_scroller import plot_session_scroller
  %matplotlib widget
  
  nwb_file = '/root/capsule/data/behavior_778077_2025-05-16_09-07-04_processed_2026-03-07_01-16-28/nwb/behavior_778077_2025-05-16_09-07-04.nwb'
  nwb = load_nwb_from_filename(nwb_file)
  
  fip = [
      ["G_0","Iso_0"],
      ["G_0_dff-bright","Iso_0_dff-bright"],
  ]
  
  nwb.df_fip = nwb_utils.create_df_fip(nwb)
  
  plot_session_scroller(nwb, fip=fip)
