another php akismet api implementation

in poking around with adding support for comments here, i looked at integrating with the akismet anti-spam service, and the existing php libraries for using it didn’t work how i wanted or brought in dependencies that i wanted to avoid. so i made a simple akismet-api package that just uses guzzlehttp under the hood.

i haven’t made a test suite or added real documentation yet, so you should consider it pre-production, but it seems to work okay.

cleantalk is another anti-spam service that we use for registrations and comments on our store website and their php library is kinda non-idiomatic and strange, too. a reimplementation of that might be in the cards.
