Interface-Definitions: All Methods return void

[leoonhitgub]

Describe the bug
Can not use your library in typescript, as long as all the method return -types are void..

for example:
export interface CanvasSignatureRef {
isCanvasEmpty?: () => void
saveSignature?: (format?: string) => void
clearCanvas?: () => void
undo?: () => void
addWaterMark?: (obj: WaterMarkObj) => void
fromDataURL?: (url: string) => void
}

Your following example-code on https://vue3-signature-pad.vercel.app/ does only work, because alert is very tolerant and can deal with the signature void. In true, the method is returning a string.

function handleSaveSignature() {
return signature.value?.saveSignature && alert(signature.value?.saveSignature())
}

To Reproduce
Steps to reproduce the behavior:
use your package in typescript, write:

let imgBase64: string = signaturePad.value?.saveSignature();

You will get the following compile-error
-->Vue: Type void is not assignable to type string

Expected behavior
The methods of your interfaces should return the same types as your wrapped library vue-signature-pad

solved by using the basic library vue-signature-pad with example for vue3 as in https://codesandbox.io/p/sandbox/broken-flower-22ot7m?file=%2Fsrc%2FApp.vue
