Natural cron "every 15th of the month"

[DannyBen]

Issue description

Trying to convert natural language to a cron expression that happens every specific day of the month.

Looking at the specs, I see that it was intended, but currently not working?

https://github.com/floraison/fugit/blob/7f4d5296e3e55e6c9853f14457af79d4b3e3a845/spec/nat_spec.rb#L48

Is it planned?

I don't even mind if it will be a little less natural language, like:

• every month on day 2 at 10:00
• every month on days 1,15 at 10:00 # twice a month 1st and 15th

if that makes it easier to implement.

How to reproduce

require 'fugit'
p Fugit::Nat.parse('Every 2nd of the month at 10:00')   #=> nil

I will implement that. Thanks.

@DannyBen Hello, I included your demand into the rework I did for the nat parser. Please tell me if it covers your need and I'll release then. If there are further cases that you'd need, please tell me. Thanks again.

Thanks a lot @jmettraux, for being open to it and for the quick update.

I tested the new sentences as defined in the specs against master and they work beautifully.

By the way - this release also fixes a bug.

With the current live release, this expression returns an invalid cron instead of nil:

Fugit::Nat.parse('Every month on day 6 at 10:00')

OK, great, I'll release in a few hours then. If you spot anything, please tell me.
