geometry package usage defined twice when "geometry" variable is set in yaml or -M option

[K4zuki]

in eisvogel.latex:

• lines 158-160:

  $if(geometry)$
  \usepackage[$for(geometry)$$geometry$$sep$,$endfor$]{geometry}
  $endif$

• line 375:

  \usepackage[$if(papersize)$$papersize$paper,$else$a4paper,$endif$margin=2.5cm,includehead=true,includefoot=true,centering]{geometry}

  ---

  line 375 defines geometry options while 158 also does it when geometry is defined in yaml header or by -M option. 158 and 375 should be exclusive.

I think 375 overrides 158 but one would be warned like this

! LaTeX Error: Option clash for package geometry.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

l.218

and this

LaTeX Warning: There were multiply-defined labels.
