Add CFP deadlines?

[lazerwalker]

Hi!

First of all, thanks so much for this! This repo + the API + the CLI tool are such a fantastic suite of resources.

They'd all be a lot more useful to me if it also contained a column for what date each conference's CFP closes; I assume this may be true for others as well!

I'm happy to put in the gruntwork of adding a "CFP Deadline" column to the table and filling in dates for the currently-listed open CFPs (with the hope that future PRs going forward to add new conferences would include that information), but I wanted to check in and make sure this is something you'd be into before I put in that effort. Especially as I assume it might also eventually necessitate a few changes to the Glitch API.

I thought of that as well, but after the initial effort of adding most of the confs in the list, I just couldn't force myself to do that ;)

I´d be happy to get a PR for this, once it has been created, I would adapt the API within an hour or so. Shouldn't be too complicated.
Another benefit would be, that the cfp-magick CLI could use those to remove entries from the list, atm. I do that kinda manually & check the open cfp´s every week or two...
