[BUG] SOSA and SSN namespace have been defined incorrectly

[edmondchuc]

In RDFLib 5.0.0 rdflib.namespace sosa and ssn have been defined as follows:

SOSA = Namespace('http://www.w3.org/ns/ssn/')
SSN = Namespace('http://www.w3.org/ns/sosa/')

https://github.com/RDFLib/rdflib/blob/master/rdflib/namespace.py#L494-L495

They need to be switched around.

Looks like it's already fixed in master.

Hi Edmond.
This was reported in #1126
and fixed in #1128

Github should have pointed these out to you as existing topics in its auto-search feature when you created this issue.

Hi Ashley, not sure why but GitHub didn't show related issues for me when I wrote this.
