Added mapping of ImGui::CalcTextSize

[KinoxKlark]

ImGui function CalcTextSize() was not mapped yet. I mapped it since I needed it for one of my projects.

This function takes a string and returns its size in pixels as a vector. It is possible to specify to ignore content after '##', and/or a wrapping width to use in computation.

I took the liberty to add default values for parameters hide_text_after_double_hash and wrap_width for quick call like: imgui.calc_text_size("MyStr")

Coverage increased (+0.04%) to 49.627% when pulling dc26bc5 on KinoxKlark:mapping/CalcTextSize into 41d7803 on swistakm:master.
