feat: new /memo badge built on Vercel KV

Created a new badge called Memo Badge. In short, you may update a memo badge with your own cron job or ci job or whatever possible method.

It's a further step of the previous /https badge that enables more usages, and more simpler to use with:

/https is an extension interface to badgen.net, you can create a badge service with your own endpoint. (e.g. tickgit).
/memo is an extension, extending badgen.net with memory. Now you can not only read a badge from badgen.net, you can also write to it!

I have been thinking about this badge for a long time, firstly I built it with Cloudflare KV, but it's like two different pieces glued together, this feeling bugs me all the time. Then Vercel announced KV, that's what I'm looking for! And finally I got some time to made the upgrade (after the migration to Next.js 13).
