Circular loading warnings

[DougEdey]

Describe the bug

When running with this gem under Ruby 2.7.2, there's a large number of (loud) warnings about circular dependency loading

I'm following the documentation from this repo and I have require 'dogapi' in my gem initialization code.

Example

/opt/rubies/2.7.2/lib/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:72: warning: /opt/rubies/2.7.2/lib/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:72: warning: loading in progress, circular require considered harmful - /Users/dougedey/.gem/ruby/2.7.2/gems/dogapi-1.44.0/lib/dogapi.rb

While I do understand this is a warning, I don't want to suppress warnings in my application as I want to ensure I don't miss out on warnings that indicate potential issues.

To Reproduce

Run the following script:

#!/usr/bin/env ruby
$VERBOSE = true
require 'dogapi'

Expected behavior

DogApi should not produce warnings when used in the recommended way

Environment and Versions (please complete the following information):
Ruby 2.7.2 (ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-darwin19])
Dogapi 1.44.0

Additional context

I poked around locally at fixing this, and I don't think that the require 'dogapi' lines are needed at all when following the documentation (I removed then with bundle open dopgapi and saw no adverse effects to my tests)
