Fix sep:"none" and mapsep:"none"
...
According to the README.md, a value of `"none"` for the `sep` tag (for
slices) and `mapsep` (for maps) is meant to disable the separator that
would allow multiple entries to be added from a single argument.
However, using `"none"` just set the separator to the rune `'n'`.
Fix the parsing of the tag, and also update `SplitEscaped` to not split
with a separator of `-1`.
Add a new test for the new cases.

Decoders are now field mappers.
...
Mappers are responsible for mapping from command-line input to Go. This
is typically just decoding, but also includes other information such as
if the field is a bool.
