go mod tidy: go.mod file indicates go 1.17, but maximum supported version is 1.15

Look like this project only work with go-1.17 while default go rpm on centos 7 is only 1.15.

• Still don't know how to fix this compilation error after reading R1.

[pi@centos7t01 scan4log4shell]$rpm -qa |grep golang

Anyway you can support building this tool using golang-1.16 ?

• RL8.5 only have version up to 1.16 from appstream.

• changing version in go.mod file seems fix the issue and I was able to get a binary.
