Support React.memo

[novemberborn]

Detect memoized elements & dereference their underlying type. Format such elements with a different annotation, similar to function types. Retain backwards compatibility with elements serialized before React.memo support was added.

Fixes #16.

Hi, is there any chance to get this PR merged in the near future?

#16 is still preventing us from performing snapshot testing of memoised components with react-test-renderer and AVA...

Thank you.

I haven't looked at these libraries in a long time now… will have to remember the impact that making changes here may have on AVA. Plus do some general maintenance. Maybe I'll have some time this weekend.

@nodaguti if I recall, this is a breaking change. I don't really have the time to deal with that. So instead, avajs/ava#2428 proposes to make this configurable. The @ava/react package can then pull in a newer version of this plugin.

I'll let you know when there's something to test 😄
