Writer for LinearContinuousSystem

[schillic]

I am not sure if this fits in the package because it is the opposite of a parser.

I chose the name writesxmodel because there is readsxmodel already.

Example:

julia> A = rand(3, 3) .-0.5
3×3 Matrix{Float64}:
  0.277972  -0.266285   -0.351089
  0.408685  -0.153038   -0.300954
 -0.20927    0.0107524   0.431776

julia> S = @system(x' = Ax)
LinearContinuousSystem{Float64, Matrix{Float64}}([0.27797173780884044 -0.2662850480574015 -0.35108891420605515; 0.40868455933584547 -0.1530378648466495 -0.30095366007442914; -0.2092704508354004 0.01075236731040552 0.4317763365948508])

julia> writesxmodel("test.xml", S)

test.xml (manual line breaks in the flow block for readability):
