Thomas Guillemard b126ea48c6 Support HomeBrew Loader (#577)
* Make it possibles to load hb-loader and hb-menu

One issue remains with hb-menu homebrew icons because of SIMD issues
(libjpeg-turbo related) and netloader doesn't work.

* Implement GetApplicationControlData

* Fix shared fonts for NSO/NRO

* Add homebrew NRO romfs support

This readd the NRO support by parsing the ASET header

* Address comments about HomebrewRomFs

* override Dispose in homebrew romfs stream

* Use a struct for file timestamp

* Simplify positional increments in GetApplicationControlData

* Address comments

* improve readability of the memory permission check in SetProcessMemoryPermission

* Fix previous broken check

* Add address space checks in SetProcessMemoryPermission
