`exportAsync` function returns Uint8Array instead of SVG string when used with `.then()`

I’m trying to use the exportAsync function to export a Figma node as an SVG file in my plugin. When I use await, the function returns the SVG code as a string, but when I use .then(), it returns a Uint8Array object instead.

After some investigation, I realized that the exportAsync function returns a Uint8Array object representing the binary data of the exported file. When I use await, the Uint8Array object is automatically converted to a string using the default character encoding, but when I use .then(), I need to manually convert the Uint8Array to a string.

I suggest that the exportAsync function should always return the SVG code as a string, regardless of whether it’s used with await or .then(). This would make the API more consistent and easier to use.

In the meantime, I found a workaround for this issue by manually converting the Uint8Array to a string using the following code:

const svgString = String.fromCharCode.apply(null, uint8Array);

I hope this helps other developers who encounter the same issue.
