Update license automation

[bpmooch]

Update automation scripts for adding license headers to files. Also shortens the length of the headers to take up less lines in each file.

Moving forward, when you add new files, simply run make headers before submitting your pull request. You can also manually run DRY_RUN=1 ./hack/headers-write from the root of the repo to get a list of the changes that make headers is going to perform

closes #468

i feel like these three commits can be merged without losing any useful information, and given they fix issues with the first commit maybe a merge is appropriate? :)

do you mean squash or merge?

I don't know... whatever GitHub does... probably squash.

were you asking me not to hit the "update branch" button or not to squash on merge?

I can't see what is causing the failure here. feels like generated code is linting badly. maybe we suppress the lint check?

Is it ok to keep the small commits and rebase them over main? I am going to be removing an amount of things in my fork and doing things in small commits helps me maintain parity with upstream

If not, no worries, let's just get this merged and I'll figure it out after

edit: after fiddling with my setup, I can make sure my pr's are squashed to a single commit in the future, sorry for the inconvenience

i think rebasing this onto the base branch should resolve the issues.

woo!
