Allow access to Yomitan features via cross-extension communication

[killergerbah]

Hello, I am the maintainer of asbplayer, a sentence-mining browser extension for streaming video.

I do not have experience with this API myself but based on this documentation, it looks like it would relatively easy to expose an entry-point into Yomitan code that's callable from an extension like asbplayer. In particular, I would love if it were possible to extend asbplayer with some of Yomitan's flagship features, such as lemmatization and dictionary word lookups. Most users use asbplayer in combination with Yomitan anyway, so ideally this would be one extra step to make sentence-mining on asbplayer nearly on par with similar software like Migaku. Currently, asbplayer implements a workaround via a WebSocket server to achieve related behavior.

I think it's totally fine to implement such an interface, but I think it will take a contribution from someone outside of the maintainer list for it to happen, basically because it's a big chunk of work and therefore requires someone motivated to work on it. We are happy to review.

Thanks for the response. I may take a stab at this when I am able to find the time.
