Skylib module containing convenience interfaces for select().
selects.with_or(input_dict, no_match_error)
Drop-in replacement for select()
that supports ORed keys.

```build
deps = selects.with_or({
"//configs:one": [":dep1"],
("//configs:two", "//configs:three"): [":dep2or3"],
"//configs:four": [":dep4"],
"//conditions:default": [":default"]
})
```
Key labels may appear at most once anywhere in the input.
PARAMETERS
RETURNS
A native select()
that expands
("//configs:two", "//configs:three"): [":dep2or3"]
to
"//configs:two": [":dep2or3"],
"//configs:three": [":dep2or3"],
selects.with_or_dict(input_dict)
Variation of with_or
