filename with the files API is truncated to the base name

[jlewi]

When uploading a file I set a filename with a path such as "docs/techdocs/content/docs/overview.md". But the file ends up being named
"overview.md".

I upload a file like so

    fParam := openai.FileParam(fileData, info.vsName, MarkdownMimeType)
    
    fileParams := openai.FileNewParams{
    	File:    fParam,
    	Purpose: openai.F(openai.FilePurposeAssistants),
    }    

It looks like the problem is here

openai-go/internal/apiform/encoder.go

Line 319 in 16aac50

filename = path.Base(named.Name())

filename is being set to base

Thanks for raising, this will be a nice fix. I'll review the PR
