Fugit::Cron#next_time works incorrectly with "every second day" and "mon-fri" combo

[n-gb]

Issue description

I've noticed that 0 0 */2 * 1-5 doesn't work as expected - it seems to ignore the "every second day" cron part

How to reproduce

require 'fugit'
c = Fugit.parse('0 0 */2 * 1-5')
p c.next_time('2022-08-09').to_t.to_datetime.to_s

produces:

"2022-08-10T00:00:00+03:00"

Expected behaviour

"2022-08-11T00:00:00+03:00"

Hello,

please read https://github.com/floraison/fugit#the-first-monday-of-the-month

It's counter intuitive, but when both day-of-month and day-of-week are specified, they're ORed, not ANDed. Fugit works correctly.

Kind regards.

Thank you, @jmettraux !
