Support the ability to get the line number where the nginx directive is located.

This PR is for Issue: #59, which supports parsing of nginx directives to get the line number in the configuration file where the directive is located.

I hope it will be merged.

I found that the warehouse small version number change a little slow ah, in fact, many features may last about a year to hit the tag, suggest 1 ~ 2 weeks can be sent some changes in the small version.

When go get gets the code, actually go mod will automatically pull the code repository of the larger tag, but you need to use v2.0.1 this kind, you need to tag with v prefix.

I'm also happy to contribute code and use open source to contribute to open source.

Thanks again for the merger.
