[Feature Request] Steam style TOTP

[owariee]

On Linux, pass + pass-otp are able to generate TOTP codes for Steam in the right format cause Pass-OTP-perl implements an simple logic to change what and how many digits are used to generate the code for Steam based on the &issuer= argument being "Steam" in the otpauth URI, like this:

return totp(
    %options,
    digits => 5,
    chars  => "23456789BCDFGHJKMNPQRTVWXY",
) if defined $options{issuer} and $options{issuer} =~ /^Steam/i;

I know that is possible to change how many digits will be used to generate the TOTP code in Otp.NET, however i dont think it is actually possible to choose the "character set" that will be used to generate the TOTP.

So what i am asking for, is support for Steam style TOTP in Otp.NET, so pass-winmenu can deliver correct Steam TOTP codes.
