Visualizing DAG-CBOR with IPLD Schema (.ipldsch)

DAG-CBOR documents should have an option to visualize them against type(s) from user-provided `.ipldsch`.

## Problem

We've found UX papercut identified with @aschmahmann while trying to provide useful interface for exploring DAG built with IPLD Schema tuples.

DAG-CBOR data is just numbers, and IPLD Explorer does not provide a way of leveraging IPLD Schema `.ipldsch` definitions.

## Solution

Perhaps "Add IPLD Schema" button on DAG-CBOR pages?

Details TBD, but I envision two flows:
- Ad-hoc: User clicks the button, then selects the `.ipldsch` file from their disk, and then user selects the type to use. The schema and type choice per CID is remembered locally (cookie/localstorage)
- Permalinks: User clicks the button, enters URL of the `.ipldsch` file, selects the type to use, and both URL and type are persisted in the URL, so the view that uses schema can be shared by copying current URL.
