Update the upstream version

[ion1]

Is your feature request related to a problem? Please describe.

It would be nice to have access to whatever new optimizations and fixes Binaryen has implemented since version 99.

Describe the solution you'd like

I would like the bundled version of Binaryen to be updated to version 118.

Describe alternatives you've considered

Unless I end up encountering a specific problem for which a fix exists in a newer release, I can live with this one.

Additional context

I might be able to make a pull request. However, since massive diffs to bundled upstream code from random GitHub users are scary (cf. Jia Tan), that would probably need to be preceded by a GitHub action which verifies that the bundled code matches the checksummed upstream tarball.
