feat: pagination

Am I too stoned rn or is eza missing a feature for output pagination?

Sure, I could pipe (huh huh) to e.g. less, but then I lose all the pretty colours, don't I?

Certainly not a priority but would be dang useful when listing subdirectories ...

The issue names no files, tests, or entry points. Start by tracing eza's command-line argument handling and output path, then determine how pagination should interact with colored output and directory listings. Done should mean a documented, tested pagination feature that preserves the intended colors.
