Add go.mod

[mpfrancis]

Importing and using the Go fastnoise library currently results in the below errors using the current version of go (v1.22.1). Adding a go.mod with go version 1.21 or higher specified should alleviate these errors.

If it only requires 1.18 shouldn't it be set to that?

[mpfrancis]

I tried 1.18, there was a different set of errors requiring 1.21.

I don't know anything about Go but could that second error be fixed by making what is complaining about explicit? v1.21 looks to be fairly recent, it would better to only require v1.18

[Auburn]

Great! Thanks for the help
