NodeJS version (or supported methods)

[BrAwnyTime]

I attempted to use your library server-side in a NestJS application, but due to ZipJS throwing an error on blob is not supported by this platform specifically at jszip/lib/utils.js:352:15. It does look like this is possible.

I believe NodeJS would be support with two changes:

• if the config object was allowed to provide the type that ZipJS would use instead of hard coding blob
• if the Promise of the zip was returned from a generateXLSX(config) and the .then((blob) => Filesaver...) could be supplied on the default export which would just call the generateXLSX` function.

i'd be happy to contribute to the library if this is an acceptable solution/direction.

@BrAwnyTime Feel free to submit a PR. I've got one strict rule, that you'll see repeated through many PRs: this lib is sensitive to bundle size increases, as it's sole purpose is to create valid xlsx output as lightweight as possible :)
