@smogon is the preferred namespace for packages (eg. @smogon/calc),
but the fact that this import logic previously contained code from
two non-Smogon sources made such naming awkward. Given the damage
calc didn't end up using these sources (and the Pokémon Showdown
client doesn't either), its simpler to just remove the logic for
third party imports entirely. This allows us to remove ugly 'hidden'
JSON5 dependency, as well as `smogon.com/` namespacing on the
sources.
This commit also tidies up the package.json and type definitions to
be more robust. It makes `--access public` the default when
publishing and cleans up unpkg support.
This is obviously a breaking change, but it's also a package rename
so we get to start the version from zero there :). A corresponding
commit will be added to the client to account for these changes.
- and error 'ls' found its way into the source
- the sets/{README.md,index.d.ts} were excluded which also meant
the sets/ directory didn't exist, causing errors
- the command is `npm publish --access public` not `publish`
