Crate rgb2ansi256

This is a small Rust library to convert RGB 24bit colors into ANSI 256 (8-bit) color codes with zero dependencies and const fn. This crate was ported from ansi_colours C library v1.0.4.

By porting the library, we have the following two benefits:

• No unsafety
• Compile time calculation (no runtime overhead)

use rgb2ansi256::rgb_to_ansi256;

const MEDIUM_SPRING_GREEN: u8 = rgb_to_ansi256(0, 255, 175);

assert_eq!(MEDIUM_SPRING_GREEN, 49);

Functions
