- rename #dependencies_list to #internal_dependencies_hash
- the initial implementation returned an array but now it doesn't
- simplify usage of #tap in #internal_dependencies_hash
- remove safe navigation operator usages in #internal_dependencies_hash
- better document why implicit dependencies are not included in the API JSON
- add new test fixture formula to better test generation of uses from
macos bounds with the new internal json format
These tests cover both generating and loading formulae from the JSON
bundle. The tests are not comprehensive but they do provide a nice
sanity check that things are working as expected.
