traceapp: perform fuzzy search on all rawData keys.

With this change, you can now fully strict or fuzzy search against all of
the keys in the spans. A fuzzy search for e.g. "200" would turn up results
properly now.

Also, we implicitly limit the filter/search string to 32 characters when
fuzzy searching as Fuse is limited to that, and will raise an exception
otherwise.

The tactic used for searching against all keys, is on a per-object (i.e.
per-span) basis. This means there is one fuse search per span object. I
also tried a single fuse search, but against the uniform (i.e. common) set
of keys shared by all the objects, but not all spans share the same set of
keys (and Fuse wants a strict set of keys to search against, specifically).

A more proper long-term fix for both of these would be to: modify Fuse to
search all object keys (when none are specified in the options map), and
make Fuse responsible for searching for patterns greater than 32 characters
(whether that means slicing to 32 implicitly as we do here, or searching
for every 32-byte consecutive sets in the pattern string).
