Support for prefix/equals-ignore-case and suffix/equals-ignore-case

[rogeriosy]

Issue #, if available: https://github.com/aws/event-ruler/issues/108

Description of changes:

• Adding functionality for prefix/equals-ignore-case and suffix/equals-ignore-case with the respective unit tests, benchmarks, and README updates.
• Explicitly running the benchmarks class after mvn verify is executed. By default, the maven-surefire-plugin only runs tests with the "Test" which ends up ignoring the Benchmarks test class.

Benchmark / Performance (for source code changes):

From my mac laptop (2.6 GHz 6-Core Intel Core i7 / 16 GB 2667 MHz DDR4):
