[Bug]: VectorData with fixed name in spec

[oruebel]

What happened?

It is possible to specify VectorData with a fixed name set in the schema. However, DynamicTable.add_column currently does not honor the fixed name and VectorData.__init__ does not do so either. As such, a user is able to create a column with a custom name even if the name is fixed in the schema. This has come up as part the ndx-hed extension.

Steps to Reproduce

See the following unit test on ndx-hed which creates a HedTags column (which has a fixed name HED) using a custom name set to "Blech"
