Add a fix to work with shorthand multiple floats such as 1.2.3

This is introduced by some editors, see

So, is this part of the SVG specification, or is this just some legacy of some editors? I suppose is does not hurt to put it in, but also, I am not a fan of using recursion for something this simple. Tell me more.

It appears to be in the specification:

Similarly, for the string "M 0.6.5", the first coordinate of the "moveto" consumes the characters "0.6" and stops upon encountering the second decimal point because the production of a "coordinate" only allows one decimal point. The result is that the first coordinate will be "0.6" and the second coordinate will be ".5". - https://www.w3.org/TR/SVG/paths.html#PathDataBNF

Recursion made sense as this is a standard head | tail problem as there is no limitation the the number of “.” That can appear (though in reality I have only seen 4)

I have incorporated parsing this type of float shorthand in the latest version w/o the recursion. Thank you for bringing it to my attention.
