Make dataprep fcl generation work for all (or most) prototypes

[dladams]

The duneproc command provides fcl key dptools_XXX to allow users to select the dataprep sequence at run time but this does not work for all prototypes because the syntax for referencing a sequence varies. DUNE/dunedataprep#2 addresses the latter. Once this is in place this key or another should be made to work with all conformant sequences.

Last push resolves this issue. (Comment should be "Add duneproc key...")

I am modifying duneproc to drop the dptools fcl key (i.e. support for pattern dptools_XXX) and replace it
with a dpseq key with pattern

dpseq_<DET>_<SEQ>

that selects sequence <SEQ> for prototype detector <DET>, i.e. with the convention described in DUNE/dunedataprep#2, i.e. matches the pattern

data.<DET>_dataprep_seqs.<SEQ>

In addition, the dunedataprep file pdsp_data_sequences is added to run_dataprep.fcl so the pdsp sequence definitions are available when duneproc processes pdsp data.

Changes are committed in version 2.4.0 of duneproc.
