InstallAPI takes a json list of headers that is typically generated from a build system like Xcode based on a project's attributes. Sometimes, maintainers may want to alter this for tapi input. Using e.g. `--extra-public-headers`, users can manipulate what headers will be used for TBD file generation.

InstallAPI takes a json list of headers that is typically generated from a build system like Xcode based on a project's attributes. Sometimes, maintainers may want to alter this for tapi input. Using e.g.
--extra-public-headers, users can manipulate what headers will be used for TBD file generation.
