refactor: move from deprecated pkg_resources

[JGSweets]

this pr:

• refactors out a deprecated library that is removed in the latest setuptools
• refactors to move resources into the DP package
• updates setuptools to utilize include_package_data instead of data_files
• limit pandas due to compatibility issues <3.0.0
• aberrations between scipy versions cause slight differences past the 10th decimal. use almost to validate
  • due to cdf on p-values

@ryanSoley Can we get a review on this? It will allow DP to continue working with new setuptools.

Otherwise, this library will not work in system that utilize the most up to date setuptools
