Important
If you run the regex against untrusted user input, it's recommended to truncate the string to a sensible length (for example, 50). And if you use this in a server context, you should also give it a timeout.
I do not consider ReDoS a valid vulnerability for this package. It's simply not possible to make it fully ReDoS safe. It's up to the user to set a timeout for the regex if they accept untrusted user input. However, I'm happy to accept pull requests to improve the regex.
