Initial release of FLI - really tiny and fast (like a ) directory listing tool.

Initial Why: need some easy readable ls like tool for rpi to use via ssh. Current Why: check if with Rust one can build core utils like tools faster and smaller.

- Size: 18K - RPI ZERO W 51KB - Mac

- Default mode streams readdir() => stdout with zero heap allocation.

- Nice readabilty thx to ( and ) instead of text coloring

- Written in no_std rust + libc.
