Update npm package

[w1nte]

The npm package hasn't been updated for a while. @Scimonster @photopea, is it possible to update the dep?

Unfortunately, the version in the npm package contains a bug where the encoding of the cmap leads to an unexpected EOF.

@w1nte you should probably open a PR and check the possible breaking changes of pako

@Sharcoux I didn't mean updating the UPNG.js dependencies. The UPNG.js npm package was last published in 2017 and isn't quite up to date. Only the package collaborators can publish a newer version.
