Crate tracing_span_tree

Consumer of tracing data, which prints a hierarchical profile.

Based on https://github.com/davidbarsky/tracing-tree, but does less, while actually printing timings for spans by default.

Usage:

tracing_span_tree::span_tree()
    .aggregate(true)
    .enable();

Example output:

8.37ms           top_level
  1.09ms           middle
    1.06ms           leaf
  1.06ms           middle
  3.12ms           middle
    1.06ms           leaf
  3.06ms           middle

Same data, but with .aggregate(true):

8.39ms           top_level
 8.35ms    4      middle
   2.13ms    2      leaf
