Describe the bug

ghz is rounding the sfixed64 integer, which can result in confusion and incorrect test results.

1000000000000000089 is rounded up to 1000000000000000100.

10000000000000089 is rounded down to 10000000000000088.

Server log:

Id:  10000000000000089
Id:  1000000000000000089

To Reproduce

See this repository: https://github.com/themreza/ghz-test-sfixed64/tree/main

Expected behavior

The request sent to the server must match the call data argument.

Environment

• OS: Ubuntu 20.04
• ghz: v0.117.0
