_aliases not exist before assigning tag to it

[ztq1996]

When I run columnmapper, it gives me this. I believe I have encounter this multiple time, a quick fix would be check if _aliases exist, if not, initiate one.

File /hildafs/projects/phy200017p/ztq1996/ztq1996/RAIL/rail_base/src/rail/core/stage.py:291, in RailStage.set_data(self, tag, data, path, do_read)
    289 aliased_tag = data.tag
    290 if tag in self.input_tags():
--> 291     self._aliases[tag] = aliased_tag
    292     if data.has_path:
    293         self._inputs[tag] = data.path

AttributeError: 'ColumnMapper' object has no attribute '_aliases'

I think that you have some other problem, maybe the wrong version of ceci, or a bad __init__, self._aliases is _always made in the PipelineStage c’tor, see here: https://github.com/LSSTDESC/ceci/blob/f51c74b3503f93ab8d998235358e47fbc85676f6/ceci/stage.py#L98 ceci/ceci/stage.py at f51c74b3503f93ab8d998235358e47fbc85676f6 · LSSTDESC/ceci github.com

Pretty sure this was fixed with all the ceci updates.
