Git scripts: checks commit sizes for entire repo and specific hash

[mickeygousset]

This pull request introduces two new bash scripts to analyze Git commit sizes. The first script analyzes the size of a specific commit, while the second script analyzes all commits in a repository and generates detailed logs and reports.

• git-commit-analyzer.sh: This script takes a commit hash as an argument and analyzes the size of that specific commit.
• git-repo-commit-analyzer.sh: This script analyzes all commits in a repository and generates detailed logs and reports, including:
  • A CSV list of all commits, their sizes, and number of files in the commit
  • A report of all commits over a certain size, including files, files sizes, and total commit size
• Updated README.md
