v0.1.5: fix(js): use replacement character on invalid decode (#25)

When decoding incorrectly encoded content, the binding now panics and
takes down the entire JS script. This change replaces the incorrect
sequence with the U+FFFD replacement character (�) in the content. This
is most often the desired behaviour.

Closes #20
