Let's add a test which has

• three measurements for a station with 1 byte long name A
• three measurements for a station with 1 byte long name B
• three measurements for a station with 100 byte long name A
• three measurements for a station with 100 byte long name B

This is to make sure the full range of name lengths is covered properly.
