Add missing PURL type to registry mappings

Adds support for 12 additional package ecosystems (bower, brew, carthage,
clojars, conda, cpan, cran, elm, hackage, julia, pub, puppet) to match
default registries from ecosyste.ms API. Also fixes typo in cocoapods
registry URL.

Includes test cases for all new mappings.
