All packages release 2.1.1

Bug fix ([#77](#177)): dependency on the
`Nullable` package was not declared with `PrivateAssets=all`,
leading to that showing up as a dependency. This would break users
who explicitly have a dependency on an older version of `Nullable`.

This fix shouldn't break anyone, as far as we're aware.
