Added basic typings for typescript

[lordnox]

These are just the basics to have typescript not complain about missing untyped module.

I sadly don't have enough time to finish the types correctly, may be I'll find time later in the week.

See: #41

Thank you for this module!

So... I guess this didn't quite make the merge?

@lordnox, are you able to move this into https://github.com/DefinitelyTyped/DefinitelyTyped? Development on this repo seems dead but usage is pretty high, so that seems like the only way to accomplish this.

[lordnox]

@saiichihashimoto I am actually not using this anymore either.

If there is interest you could move it yourself, however I think I would be best if someone takes over this project, maybe a fork, I'd push this change to the new repository then.

[saiichihashimoto]

I see. I don't really have time to get into this (especially with the high barrier to entry for DefinitelyTyped changes), so I'll leave this for someone else.

One more appeal to @chromakode before abandoning this.

Hi @saiichihashimoto and @lordnox. Sorry for the slow response on this -- I don't currently have bandwidth to maintain this library. In my opinion, these typings are not complete enough to merit inclusion, due to the use of the any type. I would want to see a complete translation of the PropTypes in each component (example) into TypeScript typings.

That being said, there are other reasons why I think that starting a project with react-html-email in 2021 would be inadvisable -- such as use of PropTypes, the reliance on module global configuration, and the lack of extensibility when compared to modern component libraries based on emotion and styled-components. Modernizing this codebase would not be a ton of work, but it is not a priority for me right now. I have updated this repo to note that it is no longer maintained. If you're interested in taking that on, I'd be happy to help.
