HiddenInput::new() calls tcgetattr twice

[abacabadabacaba]

Here:

rpassword/src/lib.rs

Lines 76 to 77 in 49e3f3a

	let mut term = safe_tcgetattr(fd)?;
	let term_orig = safe_tcgetattr(fd)?;

This makes an extra syscall, even though the value can be just Copyed.

Indeed, you're right, thanks for pointing it out! 👍

Feel free to provide a pull request with a fix. I don't have time to work on this at the moment.
