Unable to import FreeRADIUS dictionaries

I am invoking the client with the following code

from pyrad.dictionary import Dictionary
from pyrad.client import Client

client = Client(server="192.168.1.1", secret=b"test", dict=Dictionary("/usr/share/freeradius/dictionary"))

And I get following error

pyrad.dictionary.ParseError: dictionary.rfc2865(35): Parse error: Illegal type: vsa

I changed the source code to report all the data types that are not supported in pyrad and found that these data types are not supported.

File Name	Data Type
/usr/share/freeradius/dictionary.rfc2865	vsa
/usr/share/freeradius/dictionary.rfc6572	ipv4prefix
/usr/share/freeradius/dictionary.rfc6929	extended
/usr/share/freeradius/dictionary.rfc6929	long-extended
/usr/share/freeradius/dictionary.rfc6929	evs

It appears that all of these data types are part of some RFC, Maybe, they should be added to pyrad.dictionary.DATATYPES?

After updating the code to add these datatypes, I get the following error:
