Add utility method to spectrum

fix(lib): fix potential command injection in `title` and `spectrum` functions The `title` function unsafely prints its input without sanitization, which if used with custom user code that calls it, it could trigger command injection. The `spectrum_ls` and `spectrum_bls` could similarly be exploited if a variable is changed in the user's shell environment with a carefully crafted value. This is highly unlikely to occur (and if possible, other methods would be used instead), but with this change the exploit of these two functions is now impossible.

Added the spectrum_bls function, which prints all 256 colors set as the background. We can easily see which color we want to set when changing the PS1 shell variable, since the colors are more distinctive.
