[Suggestion]: Add ability to customize offset value for translate attribute for both coordinates.

[vitaliiorlov]

Hello!
In my project, I need to use different values of offset to embed the generated non-standalone QR code into another SVG file.
I need to use Nokogiri to customize this value in generated io.

If it is possible, could you please add ability to set offset for x and y?

lib/rqrcode/export/svg.rb:82

@result << %{<path d="#{path.join}" fill="#{color}" transform="translate(#{offset},#{offset}) scale(#{module_size})"/>}

Thank you!

@vitaliiorlov thanks for your suggestion. Let me have a think of how we could do this without breaking existing usage.

PS I am welcome to PRs if you already have a solution.
