[Bug]: Lack of error when writing containers that have no mapping in the TypeMap

[rly]

What happened?

See rly/ndx-pose#36 for a MWE.

An informative error should be raised when a user tries to write an AbstractContainer object or really any object within the file hierarchy that is not known by HDMF (e.g., it is mapped to a spec or it is a DataChunkIterator or DataIO object -- there may be others in this category).

This is particularly bad in the example above where the user imports an extension after creating the IO object, so the IO object does not know about the extension, and then the user adds extension containers to the file and tries to write the file. HDMF/PyNWB writes the file without those extension containers and raises no warning or error.

Steps to Reproduce

See above.
