chore: add edition = "2018 to Cargo.tomls (#132) 
## Motivation

#122 updated all crates to use Rust 2018 syntax, but I neglected to add
`edition = "2018"` to the `Cargo.toml`s. 

## Solution

This fixes that.

Overview

tracing is a framework for instrumenting Rust programs to collect structured, event-based diagnostic information. This crate defines the core primitives of tracing.

The crate provides:

  • Span identifies a span within the execution of a program.

  • Event represents a single event within a trace.

  • Subscriber, the trait implemented to collect trace data.

  • Metadata and Callsite provide information describing Spans.

  • Field, FieldSet, Value, and ValueSet represent the structured data attached to a Span.

  • Dispatch allows span events to be dispatched to Subscribers.

In addition, it defines the global callsite registry and per-thread current dispatcher which other components of the tracing system rely on.

Application authors will typically not use this crate directly. Instead, they will use the tracing crate, which provides a much more fully-featured API. However, this crate's API will change very infrequently, so it may be used when dependencies must be very stable.
