Examples in Readme don't work: undefined method 'next' for Fugit::Cron

[pboling]

Issue description

next isn't defined on Fugit::Cron instance.

How to reproduce

The simplest piece of code that reproduces the issue, for example:

require 'fugit'
c = Fugit.parse_cron('0 12 * * mon#2')
c.next(Time.parse('2024-02-16 12:00:00'))

Error and error backtrace (if any)

(irb):19:in `<main>': undefined method `next' for #<Fugit::Cron:0x0000000113b59078 @original="0 12 * * mon#2", @cron_s=nil, @day_and=nil, @seconds=[0], @minutes=[0], @hours=[12], @monthdays=nil, @months=nil, @weekdays=[[1, 2]], @zone=nil, @timezone=nil> (NoMethodError)

Expected behaviour

require 'fugit'
c = Fugit.parse_cron('0 12 * * mon#2')
c.next(Time.parse('2024-02-16 12:00:00'))
  .take(3)
  .map(&:to_s)
    # => [ '2024-03-11 12:00:00',
    #      '2024-04-08 12:00:00',
    #      '2024-05-13 12:00:00' ]

I was expecting to continue on and get the result demonstrated in the readme, but that gives the exact same error.
