Additional types for Firebird

I'd missed these in my original PR. Additionally, this marks blobs of
the text subtype as such and as there's the possibility of additional
types being added in future that the adapter doesn't know about, it now
prints 'UNKNOWN' for unknown types.

I'm working on getting the timezone test working properly, but currently
it's crashing with an assertion error from within the driver.
