Describe

Hello @aotaduy

According to this PR, I implemented the underscoreParser function to check the uppercase word separated by an underscore, hoping you could take some time to review and release the new version to npm.

Changes

• Add new config ignoreUpperCaseUnderscore description in the README.md file.
• Implemented the underscoreParser function in the rules/spell-checker.js file.
• Add some unit tests in the test/spell-checker.js file.

Hi Thanks foir the pull request !
Is this change retro compatible ?
I mean if you dont configure anything, the plugin will behave as before this changes?

Let me test this locally

I think right now we are ignoring variables in uppercase with underscores, so te be retrocompatible we might need to set the configuration to true in order to not break projects that are actually using this plugin.

Hi @aotaduy

Thanks for your reviews, I've updated some changes below:

• Rename config ignoreUpperCaseUnderscore to enableUpperCaseUnderscoreCheck.
• Adjust underscoreParser() function condition logic.
• Add more unit tests to cover those scenarios.

Kindly Review :)
