Improve time offset implementation

[Tortar]

this improves the time offset implementation, the collected dataframe is no more modified, the points are just moved in the plots

I verified it works correctly by running and verify the working of

using Revise
using Agents, GLMakie
using AgentsExampleZoo

model = AgentsExampleZoo.daisyworld(;
    solar_luminosity = 1.0, solar_change = 0.0, scenario = :change
)

daisycolor(a) = a.breed # agent color
agent_size = 20    # agent size
agent_marker = '✿'  # agent marker
agentsplotkwargs = (strokewidth = 1.0,) # add stroke around each agent

heatarray = :temperature
heatkwargs = (colorrange = (-20, 60), colormap = :thermal)
plotkwargs = (;
    agent_color = daisycolor, agent_size, agent_marker,
    agentsplotkwargs = (strokewidth = 1.0,),
    heatarray, heatkwargs
)

params = Dict(
    :surface_albedo => 0:0.01:1,
    :solar_change => -0.1:0.01:0.1,
)

using Statistics: mean
black(a) = a.breed == :black
white(a) = a.breed == :white
adata = [(black, count), (white, count)]
temperature(model) = mean(model.temperature)
mdata = [temperature, :solar_luminosity]
fig, abmobs = abmexploration(model;
    params, plotkwargs...,  adata, alabels = ["Black daisys", "White daisys"],
    mdata, mlabels = ["T", "L"]
)
fig

it's probably better if we add a slightly modified version of this to #1001 but it doesn't work as intended there because the branch already doesn't work correctly, so first that should be fixed

Can you please do this PR on the existing branch of PR #1001 ?
