`parsed-smile-seq` actually parses JSON

[nilern]

Note on using non-byte-based sources/targets (char based, like Reader and Writer): these can not be used for Smile-format documents, and thus will either downgrade to textual JSON (when parsing), or throw exception (when trying to create generator).

Looks like parsed-smile-seq should take an InputStream instead. That would fix the bug but is a breaking change.
