feat: move internal regular expressions to static properties

[vaporoxx]

Please describe the changes this PR makes and why it should be merged:

This moves the regular expressions used in the DataResolver class to static properties for external use.

Status and versioning classification:

• I know how to update typings and have done so
• This PR changes the library's interface (methods or parameters added)

Using a static global regex with RegExp#exec will store a lastIndex on the object which messes with further calls to exec on different strings.

We'd either need to clone the regexp before scanning the string or use String#matchAll which seems to be supported on node v14 (node.green with string matchAll) and does that internally. (See mdn on Regexp.exec() and matchAll())

I didn't really test either, so feel free to correct me if I am wrong.

@SpaceEEC I was able to reproduce the problem you mentioned, tested it and it should be fixed now
