GHSA-MWV9-GP5H-FRR4 Sveltejs devalue's `devalue.parse` and `devalue.unflatten` emit objects with `__proto__` own properties

In some circumstances, devalue.parse and devalue.unflatten could emit objects with proto own properties. This in and of itself is not a security vulnerability and is possible with, for example, JSON.parse as well, but it can result in prototype injection if downstream code handles it incorrectly:...
