Subject: 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.---
