hepdata: consider adding a pkg+cmd to inspect/retrieve data from HEPData

[sbinet]

like is done in HEPData/hepdata-cli.

Hi @sbinet, Is this issue still valid? And do we want like a commandline application for being able to downloading and retreiving data from HEPData for this issue just like as implemented in HEPData/hepdata-cli? Do we want the same CLI args etc with this app or should I discuss a proposal here first?

yep, it's still valid.
to start with, I think I would put the code under x/hep/cmd/hepdata-cli with possibly an internal package (to hold the Client type) under x/hep/cmd/hepdata-cli/internal/hepdata.

thanks for the offer :)
