V4.2.1 Release

[mukunku]

Summary

This PR:

• Optimizes AudioPlayerDataGridViewCell so every cell doesn't open an audio output device connection initially and waits for the user to click Play.
• Incorporates Make the audio player actually render #191 and Format filter query values with invariant culture #190
• Sharpens the .editorconfig to be more opinionated. As a consequence this PR has A LOT of changes to update code styles.
  • Over the years I've changed how I write code so the repo code wasn't very uniform. It should be a lot more consistent now.
• Parquet.NET has had a major v6 release which has proven difficult to get working with how our app uses it. So in order to obtain the fix for [BUG] Exception when a column only contains nan values #189 which was published recently, I created a forked package with a cherry-pick of that fix in it.
  • This is a temporary solution until I can integrate the breaking changes into our app
