Merge branch '111-dev-refactor-text-corpus-api-with-conduit-alp' of ssh://gitlab.iscpif.fr:20022/gargantext/haskell-gargantext into dev

This is for debugging purposes for the Prelude.read error.

Instead use Text.Read.readMaybe and panic with custom error message.

NOTE This doesn't compile yet.

This still isn't optimal because in our code we use lists, so this
will fetch everything (using conduit), coerce into a list and then
process.
