Describe the bug my pr https://github.com/wswebcreation/multiple-cucumber-html-reporter/pull/148

html output file naming bug. my mother tongue is Korean. i want to make html file by Korean

now it is only possible by English

feature.id = `${ idPrefix }${ feature.id }`.replace(/[^a-zA-Z0-9-_]/g, '-');

if feature is 로그인 테스트 it is become ------.html file not 로그인-테스트.html. i want to fix this. html file name formatting by white place.

feature.id = `${ idPrefix }${ feature.id }`.split(" ").join("-");

To Reproduce make feature name by not English.

Expected behavior The output file name will be --------.html
