zarr.api.asynchronous.open_like is broken #3352

this function is intended for creating new arrays similar to existing arrays, but it has a few problems, the most significant being that it attempts to invoke open_array without passing a mode keyword argument, which errors. It's actually hard to tell what mode=None does in this context? I think the ultimate behavior might be store-specific, but I suspect it defaults to r for memory storage. This means open_like can only read existing arrays, which defeats its entire purpose.

We should either fix this function or remove it.
