"assertSnapshot" should add support for wildcards

> One more thing I'd love to see is an alternative serializer provided as an exported function - the serializer should match using wildcards, ie. we want to assert the shape of the object but certain values don't need to match exactly. This is useful if there are dates/time measurements.

> Wildcard matching is powerful and desirable feature (We already needed something like this in our test cases. [ref](https://github.com/denoland/deno_std/blob/3b7aca1842a697daee7833310ff1bb9c049c73ea/testing/snapshot_test.ts#L106-L109)).
