speeding up clorm

[florianfischer91]

I would like to ask if clorm could be shipped with the possibility to compile it down to c/c++ (using cython)? I saw that pydantic also provide this feature and they are talking about a performance improvement of about 30-50%.
I played around a bit and with small changes in the source code (still valid python) i was able to compile it with cython. Running some benchmarks (with files in profiling-dir) looks quite nice especially when looping comes into play, f.i. creating and adding 500k facts to a factbase is about 38% faster or querying a factbase to find one element is about 32% faster.
For the full cython vs non-cython benchmark compare these two files
noncython.md
cython.md

If you like it just let me know and i'm keen to create a PR.
