sclog 0.5.0

A fast, simple, dependency-free logging library for Rust.
Documentation
# Simple Customizable Logging 

### Features
- super simple
- dependency-free
- no_std support (but expects alloc crate)
- thread-safe
- panic-safe (crash-safe)
- fast
- covers most needs
- fully customizable
- flexibility (multiple handlers simultaneously, adjust level at runtime)
- macro-based
- automatic source location tracking (file:line)
- environment variable configuration (SCLOG_LEVEL, std only)
- chaining for Result and Option with LogUnwrap trait

### Usage: 
```rust
use sclog::{LogLevel, hook_log_handler, log_info, LogUnwrap};


fn main() {
    // 1. Hook your handler
    hook_log_handler(|ll, f, ln, args| println!("{} ({}:{}): {}", ll.as_str().to_lowercase(), f, ln, args));

    // 2. Log messages
    log_info!("Server started on port {}", 8080);
    // Output: [INFO] [main.rs:12] Server started on port 8080

    // 3. Smart unwrapping with location-aware logging
    let result: Result<i32, &str> = Err("database error");
    let val = result.log_unwrap_or(0); // logs error at [main.rs:16] and returns 0

    // 4. Panic/Abort with logging
    log_abort!("Critical failure!");
}
```
