version bump 0.5.0: cleanup

- removed ssf_node.js: scripts should define DO_NOT_EXPORT_SSF to prevent export
- added ssf binary
- updated frac to 0.3.0
- entire table can be pulled and saved
- choose_fmt and format functions can take an external table
- LICENSE year updated
- removed unused tests

The script will manipulate `module.exports` if available (e.g. in a CommonJS

`number`, the internal table (and custom formats) will be used. If `fmt` is a

`.parse_date_code(val, opts)` parses `val` as date code and returns object:
