spomky-labs/otphp: Unbounded digits parameter in a provisioning URI triggers an uncaught DivisionByZeroError in OTP generation

Summary The digits parameter parsed from a provisioning URI is validated only with a lower bound $value 0 and has no upper bound src/OTP.php:353-357. OTP generation computes $code % 10 $this-getDigits src/OTP.php:283. When digits is large enough that 10 digits overflows PHP's integer range and th...
