orbi_plot_shot_noise needs a Compound column

[brettdavidheiser]

IsoX always made a compound column. The new way to read raw files does not. This makes you have to add a compound column to go from analyze to plot.

`raw_files <- raw_files |> orbi_identify_isotopocules(
isotopocules = c("M0" = 90.0548, "15N" = 91.05199, "13C" = 91.05831, "2H" = 91.06123, "13C15N"= 92.05534, "18O" = 92.059, "13C13C" = # 92.0614))

df_w_blocks|> orbi_filter_files("UNM_std_016")|> orbi_analyze_shot_noise()|>
orbi_plot_shot_noise() #This has an error

df_w_blocks|> orbi_filter_files("UNM_std_016")|> orbi_analyze_shot_noise()|> mutate(compound ="Ala")|>
orbi_plot_shot_noise()`
