 Expects the asc binary in `node_modules/assemblyscript/bin/asc`, but it now is in `node_modules/.bin/asc`.
 
 I think the problem is that the (rather old) matchstick-as package depends on an old assemblyscript version, see https://github.com/LimeChain/matchstick-as/blob/main/package.json#L12 . Can't pnpm reconcile that?

None of the issues highlighted are introduced by this PR though.
