Add Vue example

[mipo1357]

Added example of using mupdf from vue through worker.

I have a vite config set up to copy the necessary files from the mupdf library. Those files are referenced from the worker.

Clever stuff- generally works great and I like the way you embed the worker to get it working with Vue.

One thing, when I first ran I got this problem:

Error: Cannot find module @rollup/rollup-darwin-x64. npm has a bug related to optional dependencies (https://github.com/npm/cli/issues/4828). Please try `npm i` again after removing both package-lock.json and node_modules directory.

After I deleted package-lock.json and node_modules and it worked. Can we do the following with another commit:

1. Remove package-lock file
2. Add instructions to the README to do npm i before doing npm run dev ( I know most developers know this already, but I like to have it in the README just in case )
