Update criterion requirement from 0.2.0 to 0.3.0

[dependabot-preview]

Updates the requirements on criterion to permit the latest version.

Changelog

Sourced from criterion's changelog.

[0.3.0] - 2019-08-25

Added

• Added support for plugging in custom measurements (eg. processor counters)
  into Criterion.rs' measurement and analysis.
• Added support for plugging in instrumentation for internal profilers such as
  cpuprofiler which must be explicitly started and stopped within the profiled
  process.
• Added the BenchmarkGroup type, which supersedes ParameterizedBenchmark, Benchmark,
  Criterion::bench_functions, Criterion::bench_function_over_inputs, and Criterion::bench.
  BenchmarkGroup performs the same function as all of the above, but is cleaner to use and more
  powerful and flexible. All of these types/functions are now soft-deprecated (meaning they're
  hidden from the documentation and should not be used in new code). They will be fully deprecated
  at some point in the 0.3.* series and removed in 0.4.0.
• iter_custom - a "timing loop" that allows the caller to perform their own measurements. This is
  useful for complex measurements that don't fit into the usual mode of calling a lambda in a loop.
• If the benchmark cannot be completed in approximately the requested measurement time,
  Criterion.rs will now print a suggested measurement time and sample size that would work.
• Two new fields, throughput_num and throughput_type have been added to the raw.csv file.
• Added command-line options to set the defaults for warm-up time, measurement-time, etc.

Changed

• The raw.csv file format has been changed slightly. The sample_time_nanos field has been split
  into sample_measured_value and unit fields to accommodate custom measurements.
• Throughput has been expanded from u32 to u64 to accommodate very large input sizes.

Fixed

• Fixed possible invalid file name error on Windows
• Fixed potential case where data for two different benchmarks would be stored in the same directory.

Removed

• Removed the --measure-only command-line argument; it was deprecated in favor of --profile-time
  in 0.2.6.
• External program benchmarks have been removed; they were deprecated in 0.2.6. The new
  iter_custom timing loop can be used as a substitute; see benches/external_process.rs for an
  example of this.

Deprecated

• The --test argument is now deprecated. To test benchmarks, use cargo test --benches.

[0.2.11] - 2019-04-08

Added

• Enabled automatic text-coloring on Windows.

Fixed

• Fixed panic caused by outdated files after benchmark names or types were changed.
• Reduced timing overhead of Criterion::iter_batched/iter_batched_ref.

[0.2.10] - 2019-02-09

Added

• Added iter_batched/iter_batched_ref timing loops, which allow for setup (like
