...and make a small UI change so that folks won't get concerned about parsing errors.
Right now all the "undecoded extensions" noise goes into
rayhunter-daemon.log, and users get concerned about it when browsing
that through the UI.
See https://github.com/EFForg/rayhunter/issues/334
Severity levels low, medium, high are now exposed to the UI in form of
dotted, dashed and solid lines. The line on the UI represents the
highest-so-far severity seen.
Originally this was intended to be represented by Yellow/Orange/Red, but
this would mean yet another divergence for colorblind mode. This is
colorblind-friendly by default (I think...)
As part of this, simplify EventType so that it becomes a flat "level"
enum without nested variants.
There is also a new debug endpoint that allows one to overwrite the
display level directly for testing.
Each event index corresponds to an index in analyzers. But some events
may be null. We're skipping those events without incrementing the index,
leading to wrong analyzer names.
