Render data type values

## Motivation
Currently data types are only rendered in the key column of the component. But there is a need to show more detailed information about a type (at least a human readable name). There are multiple ways a type is displayed:
- via a MIME-Type
- via a PID resolvable to a data type registry (eg. 21.T11148/22f932b664aa6aa3fb5b -> http://dtr-test.pidconsortium.eu/#objects/21.T11148/22f932b664aa6aa3fb5b)
- plain text, no format

## Goals
- [ ] Get an idea of what to visualize to the end user
- [ ] Determine how to decide between type and/or PID
- [ ] Implement a children of GenericIdentifierType for use in the component

Start by reviewing the component's existing key-column rendering and how it handles MIME types, PID-resolvable registry values, and plain text. Done means deciding what users should see, defining when to display a type or PID, and implementing a child of GenericIdentifierType for the component.
