LibProsperoPKG v1.4

Changelog :

• Added ProsperoApplicationType and new ProsperoBuildOptions fields to control generated param.json DRM/badge values and optional fake-signing of ELF modules.
• The build pipeline can now fake-sign eboot.bin/*.elf/*.prx/*.sprx into fake-self before packing and restore original files afterward, with an additional in-place fake-sign helper API.
• Also fixes pfsimage.xml application-type emission to mirror param.json DRM type instead of hardcoding free.
• Extended native C interface:
  • lpp_build_package_ex with full option set (lpp_build_options struct)
  • lpp_read_self_info
  • lpp_make_fself_ex
  • lpp_make_fself_file
  • lpp_fake_sign_folder
  • app-type helpers
• README/docs updates to cover the new API and behavior.
