Release a version that does not cause Hashie conflict messages

Is your feature request related to a problem? Please describe.
The most recently released version of this gem (1.18.0) produces an error with the pinned hashie version, as seen in #41. This has been fixed in #112, but is not yet included in any released version. This has caused a huge amount of log spam that my applications must filter or suppress.

Describe the solution you'd like
A new version release that includes work completed in #112.

Describe alternatives you've considered
Currently, my workaround is to pin this gem's version via ref, like gem 'boxr', github: 'cburnette/boxr', ref: '140f0d'. However, I would prefer to rely on an official version.

Additional context
I would be happy to submit a PR to bump the version to 1.19.0, but did not see any documentation on whether that would meet the requirements for a version release. Please let me know if a PR would be welcome, or if there are other requirements that must be met before boxr can have a new version release.

Thanks for the heads up @shawnacscott! I'll cut a release as soon as I can, sorry for the headache
