Add progress meter

[roflmaostc]

Hi,

is there an option to include a progressbar for the optimization?
Something like: https://julialogging.github.io/reference/progresslogging/#ProgressLogging.jl

Best,

Now I use this:

const start_time = Ref(zeros(1))
const last_time = Ref(zeros(1))
function log_time(x)
   if x[end].iteration == 0
       start_time[] .= time()
       last_time[] .= time()
   end 
   @info "Iteration:\t$(x[end].iteration),\t total time:\t$(round(time()-start_time[][1], digits=2))s,\ttime since last iteration:\t$(round(time()-last_time[][1],  digits=2))s"

   last_time[] .= time()
   return false
end


@time patterns_vial, printed_intensity_vial, optim_res_vial = optimize_patterns(togoc(target), geometry_vial, 
GradientBased(optimizer=Optim.LBFGS(), 
options=Optim.Options(iterations=5, store_trace=true, 
                                           callback=SwissVAMyKnife.log_time)), loss)

Resulting in:

Iteration:	0,	 total time:	0.0s,	time since last iteration:	0.0s

Iteration:	1,	 total time:	0.91s,	time since last iteration:	0.91s

Iteration:	2,	 total time:	1.64s,	time since last iteration:	0.73s

Iteration:	3,	 total time:	2.38s,	time since last iteration:	0.73s

Iteration:	4,	 total time:	3.12s,	time since last iteration:	0.74s

Iteration:	5,	 total time:	3.85s,	time since last iteration:	0.74s
