polyfill

The internal library that nbt-edit uses, NBTify, uses Compression and Decompression streams.
These are not supported in all browsers. If you are using nbt-edit in a browser that does not support these streams, you will need to include a polyfill.

The reccomended polyfill is compression-streams-polyfill, as it works well with SvelteKit.

Firefox does not support these streams, and Chrome supports them only in version 80 and above.
