Refactor, adding version info and minor bug fixes

[kiddinn]

Few things done in this PR

1. Updating the version information for numpy/pandas/altair to match a more recent version (also to cut time on compiling needed for ubuntu 20.04
2. bug fix ExploreResource now checks whether an index is in a ready state before it is added to the search, so if _all is used as an index, timelines in an error state or other states are not included in the search
3. bug fix A new error condition is handled in utils.py where an attempt is made to create an index that already exists (in the case where an importer is importing a file in chunks)
4. Timesketch version information is moved out of setup.py into a separate file
5. The Timesketch Version information is now included in the metadata of a sketch export.
6. When a timeline is added to a sketch all sketch labels that are deemed "protected" are propagated to the timeline and search index (to prevent deletion)
7. Various bug fixes in the API client and resources to deal with handling an archived sketch.
8. Changing the way sketches are archived to be a status instead of a label
