Implement numblr and tumbex (alternative front-ends to Tumblr).

(my first ever issue into this repository, so apologizes for any incoming mistakes of mine 😅)
This one seems pretty promising, though the author hasn't ever put out a working instance or two of it, and I haven't gotten the faintest idea on building it.

There's also tumbex, but I don't think it's open source, much less really intended as private and insusceptible to spying.

are there any instances in the first place?

@ManeraKai We shouldn't add Tumbex as it is just like PixivMoe for Tumblr. It doesn't even proxy the request.

See the analytics it uses :

@Impeta please add some instances and then reopen this issue.
