ArrayExpressHTS ran into removed fastx-toolkit

[Steffen Möller <steffen_moeller@gmx.de>]

Hello,

fastx-toolkit https://tracker.debian.org/pkg/fastx-toolkit ran into a
bug in one of its dependencies and was removed for that reason.
ArrayExpressHTS still depends on fasta_formatter from that library.

In the meantime, Pierre has fixed that bug on that dependency of
fastx-toolkit, so I think this could go back in, right?

If we are concerned about taking responsibility for fastx-toolkit since
upstream officially declared it as unsupported, then maybe this would be
something for https://fasttrack.debian.net/ and its reverse dependencies
like ArrayExpressHTS with it, then? But since complicates everything, I
would like not go that route.
