calculate min and max length for regex, if any

[swanandx]

TryHackMe flag will be min 3 ( as it must have thm in it ) and there is no max limit.

YouTube Video ID will be 11 characters long, ( n92YrzELBJU )

We need a list with this for every regex.

• if there is no fixed length, put *
• if min but no max, use 3-*
• can only be 8 or 10, use 8/10
• exact length 11, use 11

Many regex identify text which have fixed size range, if we filter based on it first, we might optimize our algorithm.
Suggestions are welcomed for other ways to optimize.
