Remove local pyceres and HighFive

[Phil26AT]

• remove local pyceres folder and add pyceres as a dependency
• move HighFive from local fork to BlueBrain's official repository
• remove redundant glog bindings --> now located in pyceres
• Require ceres >= 2.1

Note: This commit changes submodules. If you pull these updates into an existing repo, run git submodule update --init --recursive before installing.

You also need to install pyceresfrom source (similar to pycolmap):

git clone --recursive git@github.com:cvg/pyceres.git
cd pyceres
pip install -e .
