Any chance you could add typescript support to sparkline?

[Laro88]

sparkline works fine in Vue3 but vite is not happy with the lack of .d.ts file. I have handcrafted a .d.ts file for the sparkline function:

//sparkline.d.ts in the dist folder
export  default function sparkline(svg_html_ref: any, data:any[], options?:any) : void;
