http.Request be changed to interface to avoid extra conversion for fasthtttp or hertz.

[li-jin-gou]

Summary

Hertz has a lot of users currently using sentry, some of them are sensitive to interface latency, we found that sentry-go only supports setting http.Request but not hertz's Request, and we need an additional conversion.

Motivation

If it can be changed to interface, we can remove this conversion, bringing latency and CPU performance gains.
It may not be an interface, or there may be other options that don't require the conversion of http.Request.
