Added support for half precision floating point numbers in MRCs

[oierlauzi]

Xmipp is now able to read and write from FP16 (mode 12) MRC files. To do so, I have integrated the half 2.2.0 library into Xmipp's codebase. This library will use intrinsic instructions to perform the conversion when available.

[oierlauzi]

I am pending to get some FP16 MRC files to be able to test changes and make definitive this pull request.

Codesmells are coming from the half library.

The half 2.2.0 is compatible with C++17?, the web says

supporting C++11 features Not sure what it means

The most of the yes but

It should be. "supporting C++11 features" means that it takes advantage of modern C++ features when available (such as constexpr). AFAIK It should be compatible with any C++ version, including C++17

Ooops, fixed it. I do not why it was compiling in my machine, as there was an error there

It appears after the merge devel into the branch

[oierlauzi]

There was another compilation issue. Fixed it
