Added IFC libraries for AU and EU profiles
Also added script that was used to generate those libraries (the script is using data from https://github.com/boltsparts/BOLTS). Types of steel profiles included: I profiles, Z profiles, C profiles (known as U profiles in IFC), L profiles (both equal and unequal), hollow profiles (circle, square and rectangular).
