Unattractive group of legends and colors in subplots

[beorostica]

When getting a plot from the plot_seq() function, and then protting stacked subplots like so:

using KomaMRI
seq = read_seq(joinpath(dirname(dirname(pathof(KomaMRI))), "examples", "1.sequences", "ge.seq"))
p = plot_seq(seq); [p; p]

In the figure, the legends are grouped togheter and the colors of traces are all different, this is an unwanted behaviour.

We wish that the legends must be grouped in different places for each subplot and the color can be repeated among subplots. The legend aspect can be solved by defining a legend group and the color can be addressed be setting the colors
explicitly.
