Inconsistent style

[fire]

I would prefer the use of the Godot Engine clang format. https://github.com/godotengine/godot/blob/master/.clang-format

https://github.com/codecat/godot-tbloader/blob/master/src/map/entity.cpp uses { on a separate line and https://github.com/codecat/godot-tbloader/blob/master/src/map/geo_generator.cpp { is on the same line.
