Mateusz Pusz 9527b39005 refactor: 💥 q_* UDL renamed to _q_* 
We had some fun exploring the STD UDLs for potential collisions,
we have learnt our lesson and know how to proceed.
Now is high time to start behaving and obeying C++ rules.

    • Added absolute functions and epsilon to math.h (thanks @mikeford3)
    • Added a lot of prefixes to named units and introduced alias_unit (thanks @yasamoka)
    • Linking with Conan targets only when they exists (#98)
    • All physical dimensions and units put into physical namespace
    • CMake improvements
    • Velocity renamed to speed

    Many thanks to GitHub users @oschonrock, @kwikius, and @i-ky for their support in drafting a new library design.
