Drama filter

Sometimes you want one of the checks to not run for some of your ntoebooks. E.g. you can have one notebook that has an error, but this is expected (because you are demonstrating error behaviour).



```julia
drama_list = [
  Exclude(
      DramaSomething(),
      ["thisone.jl"]
  ),
  ...
]
```


~And the DramaContext should include notebook path~ DONE
