[tz] Atlantic/Jan_Mayen, Arctic/Longyearbyen and Europe/Berlin

[Chris Walton]

Paul,

1.
For the record, I detest the practice of linking zones across
different ISO-3166 regions.  Forcing one country to be associated with
another country is politically and culturally offensive.

2.
In 2021b you have:
  Atlantic/Jan_Mayen linked to Europe/Berlin.
  Arctic/Longyearbyen linked to Europe/Oslo.
This seems inconsistent to me.
If you insist on keeping Atlantic/Jan_Mayen linked to Europe/Berlin,
then I think that the Europe/Berlin entry in zone1970.tab should show
"DE,SJ" instead of just "DE".
