Fields are not imported if there is a colon in them

[florianwallner]

If there is a colon in fields like SUMMARY, DESCRIPTION or URL of an ics file, the fields cannot be imported and are left empty.

My versions:
Typo3: 9.5.13
news: 7.3.1
news_importicsxml: 3.0.0
php: 7.3.5

classic install

Had the additional problem that multiline description was interrupted.
Fixed both problems by changing the preg_match in the Ical.php#L199 as follows:

preg_match('/([A-Z-;=^:]+)[:]([\w\W]*)/', $text, $matches);
