Incorrect namespace for QUDT

[dr-shorthair]

In https://github.com/rapw3k/glosis/blob/master/glosis_unit.ttl#L7 the QUDT namespace (and prefix) is incorrect - it has qutd which should be qudt - its has no effect in the prefix, but is wrong in the URI

Thank you Simon for pointing this out. I will correct it for next micro release.
