get fid from filename

[chriddyp]

With our new API endpoints (https://api.plot.ly/v2/), we'll need an easy way to either get the file-id from the filename, or allow the filename and the file-id to be interchangable in the functions that we expose.

Hi - this issue has been sitting for a while, so as part of our effort to tidy up our public repositories I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our stack. Cheers - @gvwilson
