Set slice capacity based on input in `Map` and `Classes.Render` (#243) Hey! I just discovered this repo and I love being able to write templates while still having compile-time checks. I was looking through the code and noticed slices aren't currently preallocated in `Map()` and `Classes.Render()`. Preallocating will improve performance since the resulting slice won't have to be grown dynamically during the append loop.
