Installation instructions broken

[Nate711]

Hi, I'm using the latest go v1.23 and cannot install tarp using the provided installation instructions. I just want to split up a tar file for webdataset.

The issues:
go get -v github.com/tmbdev/tarp/tarp

• Error: go: go.mod file not found in current directory or any parent directory...
• Why do I need to be in a module? I think most users will just be like me and want the tarp binaries and not care about go

go install -v github.com/tmbdev/tarp/tarp@latest

• Error: The go.mod file for the module providing the named packages contains one or more replace directories....
