fix: convert MiradorImageTools to functional component to fix no image bug

[fstoe]

I converted the MiradorImageTools class component to a functional one, due the usage of hooks inside the mirador withSize HOC.

For usage i had to install a prepublish build as described by lutzhelm here.

Good catch!
I think we should wait for a fresh mirador alpha build before we resolve #51 or #38. We discussed having one this week.

@fstoe alpha4 is ready, could you include it in this branch?

[fstoe]

@lutzhelm sure :) i just updated to alpha 4

Currently the tests are failing; you will also need to remove the react-sizeme leftovers from setupJest.js and provide the MiradorImageTools component in MiradorImageTools.test.jswith asize` prop, e.g.

size={{
  width: 100,
  height: 200,
}}

oh...:/ now the tests are working again

Sorry, there is just one last thing: could you order the props alphabetically?

[lutzhelm]

... same here: could you move innerRef up to have an alphabetical order?
