1. Clone specific branch

4. Checkout PR 123 to branch called "pr123"
git fetch origin pull/123/head:pr123

5. Compare commits in upstream with current branch and create diff
git format-patch --ignore-if-in-upstream origin --stdout >  commits.patch
git format-patch --ignore-if-in-upstream origin -o folder/patch

6. Squash all commits in branch to single commit
