Hide password input

[sotpapathe]

When entering a password, all input characters appear in plaintext. For example

signet-cli version 0.0.4

Enter password:password

This could pose a security risk. After some searching I did not find any platform independent way to hide terminal input. I plan to create a pull request for Linux but I have no MacOS or Windows systems available.

For Linux or most POSIX shells I believe you can use stty to control the echo on/off.
