[Ruby] Fix Content-Transfer-Encoding binary unpacking

[sirwolfgang]

Based on my findings attempting to download PDFs with a downstream gem, I discovered that binary transferred data is never being unpacked into it's native format. This renders the results malformed. mxenabled/mx-platform-ruby#90

This PR adds a patch that simplifies the flow control of the deserialize method, while updating it to properly deserialize content from binary transfer encoding.

I have a patch of this running downstream in production.

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh ./bin/configs/*.yaml
  ./bin/utils/export_docs_generators.sh
  

  (For Windows users, please run the script in Git BASH)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.6.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

@wing328 I've gone through this a few times, and nothing changes; but it could be because some of the threads crash out on the second command:

Oh, looks like I can run just the ruby ones.

[wing328]
