Includes support for rxjs 7

[sithwarrior]

This updates the peerdependency of rxjs to include version 7.

rxjs 7 has no breaking changes that relates to backoff-rxjs, but provides benifts, such as a smaller bundle size.

btw fixes #36

Hi @alex-okrushko Sorry to bother you, but could you review this single line change?

It provides support for installing backoff-rxjs in a project with rxjs 7.

It simply updates the peerdependency to include ^7.0.0

Hey @alex-okrushko 👋

I am just here to bump this PR. I am updating to Angular 13 and it has a dependency of RXJS 7.4.0

Using ng update rxjs causes the update to fail with:

Package "backoff-rxjs" has an incompatible peer dependency to "rxjs" (requires "^6.5.5", would install "7.4.0")

@sithwarrior has awesomely got us covered with this PR 👍

Thanks for the awesome lib!

Hey @clark-stevenson and @sithwarrior. I'll update & release it soon. There is one morr change that I want to land before that.
Thanks for the PR.
