Add support for regex paste

[pomeh]

A little nice feature would be to detect when the user paste something in the input field and if it looks like a regex, automagically remove the regex delimiter, and extract optional flags.

To understand what I mean, try to paste this whole regex /^https?:\/\//ig into regex101 website https://regex101.com/.

Also, when a regex is pasted, it should automatically update the image.

What do you think ?
