Vincent Fazio 6a7d3306e4 bindings: python: chip: map names for lines requested by offset ...

Previously, lines requested by name could also be referred to by offset
when calling LineRequest.reconfigure_lines. However, lines requested by
offset could not be reconfigured by name if they had one.

Now, the name map is populated if the line has a name regardless of if
it's requested by name or offset.

To make behavior as consistent with earlier versions as possible, a line
requested by name always returns the first line on the chip with that
name. If there are duplicate line names and lines are requested by
offset, the first line in the request is mapped to the name. A line
requested by name always overrides a name mapped via an offset request.

If lines 0-3 all have the same name and a config object looks like:
  {("foo", 1, 2): None}
or
  {(1, "foo", 2): None}

Then lines 0-2 are requested and line 0 can be reconfigured by name.

If the config object looks like:
  {(1, 2): None}

Then lines 1 and 2 are requested and line 1 can be reconfigured by name.
