[Bug]: Turtle doesn't work with non-default OFS

[Szeraax]

Description

I use $OFS = "|||" so that it is easy to tell when strings have spaces vs arrays that are getting cast to string. This breaks multiple things like:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0|||0|||84|||72.746132" transform-origin="50% 50%" width="100%" height="100%">

Reproducable Steps

$OFS = "|||"
$inscribedCircle = 
    turtle id inscribedCircle width 42 height 42 turtles ([Ordered]@{
        'square' = turtle square 42 fill '#4488ff' stroke '#224488'
        'circle' = turtle circle 21 fill '#224488' stroke '#4488ff'
    })
$inscribedCircle | Save-Turtle ./InscribedCirclePattern.svg pattern

# Observe no file saved

$inscribedCircle | Save-Turtle ./InscribedCircle.svg

# Observe no actual SVG content present and bad viewBox content

```posh
$OFS = " "
$inscribedCircle | Save-Turtle ./InscribedCirclePattern.svg Pattern
$inscribedCircle | Save-Turtle ./InscribedCircle.svg

Everything works great.
