feat(calendar): support token dateformats

[lubber-de]

Description

This PR adds support to use token strings as a date formatter. It's still possible to provide functions as before.
The base idea is adopted from https://blog.stevenlevithan.com/archives/javascript-date-format

Now you can use something like

formatter: {
	date: '"Intergalactic Date:" D.M.YYYY' 
}

Usable Tokens (i compared popular big date libs like momentjs, date-fns, luxon and dayjs to make sure to basically match the same syntax)

Description	Token	Resultset
Day of Week	d	0-6
Day of Week (2 char text)	dd	Su - Sa
Day of Week (3 char text)	ddd	Sun - Sat
Day of Week (Full text)	dddd	Sunday - Saturday
Day of Month	D	1 to 31
Day of Month (Leading zero)	DD	01-31
Day suffix	S	st,nd,rd,th
Month	M	1 to 12
Month (Leading zero)	MM	01-12
Month (3 char text)	MMM	Jan-Dec
Month (Full text)	MMMM	January-December
Year	YYYY or Y	2022
Year (2 Digits)	YY	22
Week	w	1-53
Week (Leading zero)	ww	01-53
Hour (12h Format)	h	1-12
Hour (12h Format, Leading zero)	hh	01-12
Hour (24h Format)	H	0-23
Hour (24h Format, Leading zero)	HH	00-23
Minute	m	0-59
Minute (Leading zero)	mm	00-59
Second	s	0-59
Second (Leading zero)	ss	00-59
AM/PM	A	AM-PM
AM/PM (lowercase)	a	am-pm
Custom Text	Wrap in double or single quotes	Your text without quotes

I removed the ampm setting, because it is now controllable via the A or a token.

This is awesome 👍

@exoego I made the time format inside cell selection independent of the output format and provided an additional formattedDate behavior by 76b68b9

Please review again.
