fabletools 0.6.1

Small patch to progress deprecation of graphics functionality that required updating reverse dependencies to require fabletools >=0.6.0.

Breaking changes

• The autoplot() and autolayer() methods for graphics functions now require the fabletools to be attached (not just loaded). If you previously used library() to load fabletools (or fable, fpp3), your code will continue to work. We do however recommend that you also include library(ggtime) (or fpp3) for time-series graphics going forward.
