Eos-py

A major release, containing a new pose estimation algorithm, view-dependent texture extraction and a lot more minor improvements.

Highlights:
- Added a nonlinear camera estimation algorithm that directly estimates OpenGL-like rendering parameters (pose rotation, translation, camera frustum)
- A small OpenGL-like software-rendering function to render the model and textures
- Added the glm library headers for all OpenGL operations
- Parallelised the texture extraction using `std::async`
- The texture extraction computes and outputs the view-angle for each triangle
- The MorphableModel `.bin` files are now versionised (current version: 0)
- Minor fixes, added assert()'s, documentation improvements

This is a milestone release and the first version that's ready to be released to the public.

Highlights:
- fully header-only, neat, simple & modern C++ code & doxygen documentation
- affine camera pose fitting
- shape-to-landmarks fitting
- isomap extraction
- includes our public shape-only 3D Morphable Face model
- example application (`fit-model.cpp`)

Experimental - based on the latest eos (v0.15.0) and libigl versions.
Complete rewrite of the GUI with ImGui, which the libigl-viewer now uses.
It's in principle working. See here for the remaining issues: https://github.com/patrikhuber/eos-model-viewer/milestone/1

Initial release.

Please see the [main page](https://github.com/patrikhuber/eos-model-viewer) for details.

The Windows binary may or may not work on your particular system. If it doesn't, use the source code.
