Repair compatability with EnsembleKalmanProcesses v1.1.7

[odunbar]

Purpose

• Closes Problems installing the package #311 (on #main , will also create new CES release)
• Compat with v1.1.7 EKP requires new Observations framework

Content

• Updates CES examples with new Observations framework without changing functionality
• removes calls to the now-removed EKP.Observations module
• removes a useless utility dependent on old observations (and unit tests)
• extends EKP.get_rng() to remove conflicting definitions and removes a deprecated keyword for additive inflation
• updated Lorenz compat removing unnecessary pinning of FFTW in Lorenz to 1.3 (indirectly pinning EKP to 1.1.5)
• added warnings to Cloudy docs and run - that it must be run with the specific commit of Cloudy.

Misc

• Cloudy example has dependency issues, yet again.
  Trying version 0.3.0 along with EKP relaxing Interpolations dependency to 0.13 -> breaks as v0.3.0 was registered many commits after tagging 0.3.0 in Cloudy
  Trying commit b4fa7e3 (sometime 0.3.0 was tagged but before it was registered as 0.3.0) Cloudy, along with EKP relaxing Interpolations dependency to 0.13 -> works!

• I have read and checked the items on the review checklist.

All tests now pass and buildkite. Docs build, and I have also checked to ensure Cloudy example is working.
