Matlab bindings improvements/updates

[patrikhuber]

The Matlab bindings are not updated to work with v0.13.0. They probably need changes to work with Eigen matrices as well as core::Image.

Contributions for this are welcome. It shouldn't be too hard.
I currently don't have time to maintain them, as I'm only using the Python bindings (which are awesome! :-) ).

In the meantime, the Matlab bindings in v0.12.2 should work.

@Ostnie I'm going to remove your posts here as they're not at all related to eos's Matlab bindings. If there is some issue with the eos library, please open a separate issue. Thanks!

Removed wontfix for @FengZhenhua - we'll try to get to updating the Matlab bindings in the near future.

Adding this here for reference: Very valuable information. kyamagu/mexplus#14

A first set of updates (probably the most important one!) is done: The eos-matlab-fitting bindings now compile again with the latest eos version.

Open todo's:

• Add MorphableModel class bindings so that the model doesn't have to be loaded with each fit(...) call
• Improve the documentation
• Update the README.md
• Add back the eos-matlab-render bindings

Just for later reference: This post RobotLocomotion/drake#1267 (comment) has some approach that proposes to use variadic templates.

But from R2018a, Matlab has a C++ mex API now! I am currently checking it out. It's hopefully the way to go.
