Provides a cross-platform way to disable terminal echo or check if a stream is a tty.
Functionality similar to python getpass and os.isatty
Tested on Linux, macOS, and Windows. BSD will also probably work but hasn't been tested.
The windows portion uses the new official windows crate instead of the older winapi crate.
Example: Get a password
```rust use passterm::read_password; std::io::Write;
print!("New password: "); std::io::stdout().flush()?; let pass = read_password()?; println!();
println!("Your password is: {}", pass.as_str()); ```
Example: Check if standard output has been redirected
```rust use passterm::{isatty, Stream}
let istty = isatty(Stream::Stdout); if istty { println!("We're in a terminal"); } else { println!("Not in a terminal. Output was redirected >."); } ```
