Wildcard matching with regex pattern is not correctly parsing the path values

[shettyh]

Combining two related issues here. Please let me know if that is not fine, will create separate issues.

Issue 1: Path values are not correct

Endpoint: /payments/{id: [0-9]{4}}*

Request Path: /payments/4765_payID/status

Expected Path Keys and Values: { "id" : "4765", "*" : "_payID/status" }

Actual Path Keys and Values: `{ "id": "", "*": "4765_payID/status" }

I am sure there are other ways to register the same route like /payments/{id: [0-9]{4}}{local_wildcard}/* to handle the above cases but this doesn't allow /payments/1234_payID work around is to define two routes in that case. We are facing this issue as we are migrating from another router ( lua based ) to Chi and we want to keep the routes backward compatible. Does it make sense to support this usecase ? If so then i can take a initial look at this and raise a PR for the same.

Issue 2: Extension to the Issue 1, Wildcard endpoint is ignored

• Endpoint 1 : /payments/{id: [0-9]{4}}*
• Endpoint 2: /payments/{id: [0-9]{4}}/status

Request Path: /payments/4765_payID/not_status

Expected Status Code : 200 ( Path Matched )

Actual Status Code: 404 ( No route matched )

When there are multiple childs along with wildcard, it follows the path without wildcard in this case. I was thinking why not add * also in the sort function here to push the wildcards to the last ( tried locally, works fine). Please share your thoughts, i can raise the PR for the same
