ImplicitModificationWarning when aggregating data

[LuLeom]

Report

Hello,

This is not really a major bug, but I still wanted to report some warnings when using the fs.pp.aggregate_flowframes() function:

aggregated_data= fs.pp.aggregate_flowframes(
    filenames=fcs_files_list, #A list with all my .fcs file paths
    c_total=80000,
)

This results in the following warnings:

Despite the warnings, the function seems to work as usual.
