Add nullability annotations on methods

[MrIvanPlays]

since v2 migrated from subscribers to futures, we forgot to add @NotNull annotations on the return values of methods changed.

Imo we should also consider https://github.com/osundblad/intellij-annotations-instrumenter-maven-plugin to ease the workload of adding nullity annotations. It's easy to forget manual null checks when annotating.

My personal preference is to do these manually.

@lokka30 this library's about adding Objects.requireNonNull calls on fields annotated with @NotNull.

Thanks for clarifying – I'm happy to use it for that specific function. I'm being careful not to overstep with automation.
