grep-rs v2.0.0

Full Changelog: v1.0.0...v2.0.0

TLDR

• Better error handling
• Added crate clap for more robust CLI
• Added crate colored for colored output (it automatically disables itself when using NO_COLOR env var)
• Switched to edition 2024 which makes the MSRV now Rust 1.85
• Added LTO and Codegen units optimizations for faster runtime speed
• Swapped from MIT license to GPL 3.0
• Added forbid(unsafe_code) and warn(clippy::pedantic) global directives to ensure future compliance with those
• Allows passing the file path directly to the CLI (e.g. grep-rs <pattern> <file>) but STDIN still works (e.g. cat <file> | grep-rs <pattern>)
• Added -C/--case-sensitive flag
• Added -l/--line-numbers flag that shows the numbers of each line matched
• Added -c/--color flag to allow changing the color of highlighted text
• Swapped to using BufReader and iterating directly through reader.lines() to avoid putting the whole file into memory.
• Added test cases that can be ran with cargo test
• README now is more complete
