[Bug] infinite loop when excluding all symbols and strictly requiring symbols

[dillonstreator]

generate-password v1.5.1 currently has a bug which results in a max callstack size exceeded

The bug occurs when strictly requiring and then excluding those characters.

i.e.

import generator from 'generate-password';

generator.generate({
  strict: true,
  numbers: true,
  exclude: "1234567890",
});

Could we instead throw an error if the configuration is not possible?

The same error happens with the following options: { length: 6, numbers: true, strict: true, symbols: true, exclude: '' }

I also got Maximum call stack size exceeded with the following configuration:

const symbols = '$*.[]{}()?\\-"!@#%&/\\,><^\':;|_~`+=';

{
  length: 32,
  lowercase: true,
  numbers: true,
  strict: true,
  symbols,
  uppercase: true,
}

I fixed it by escaping ] to be \\] so the full string of symbols will be:

$*.[\\]{}()?\\-"!@#%&/\\,><^\':;|_~\`+=

It seems like any misconfiguration throws this error.

I also got Maximum call stack size exceeded with the following configuration:

const symbols = '$*.[]{}()?\-"!@#%&/\,><^':;|_~`+=';

{

length: 32,

lowercase: true,

numbers: true,

strict: true,

symbols,

uppercase: true,

}

I fixed it by escaping ] to be \] so the full string of symbols will be:

$*.[\]{}()?\-"!@#%&/\,><^':;|_~`+=

It seems like any misconfiguration throws this error.
