Implement new GUI and CLI, fix misc. smaller issues (#22)

* Initial commit of new UI c# component

* Initial commit of new UI frontend component

* target WinExe to hide console window in release mode, move ui exe into resources

* force single file publishing and add initial gh workflow for publishing ui

* fix workflow errors

* update dependencies and remove cxxdemangler, as it was outdated

* fix c# single file output due to invalid output path

* smaller tweaks, hack around loops in cpp type layouting

* process other queued exports even if one fails and show error message

* add basic support for processing LC_DYLD_CHAINED_FIXUPS

* ELF loading should not use the file offset for loading the dynamic section

* fix symbol table loading in some modified elfs

* add "start export" button on format selection screen, clear all toasts after selecting an export format

* embed ui executable directly into c# assembly

* only build tauri component in c# release builds

* add il2cpp file (binary, metadata) export to advanced tab

* fix and enable binary ninja fake string segment support

* add support for metadata

* unify logic for getting element type index

* fix new ui not allowing script exports other than ida

* new ui: clear out loaded binary if no IL2CPP images could be loaded

* fix toAddr calls in ghidra script target

* remove dependency on a section being named .text in loaded pe files

* tweak symbol reading a bit and remove sht relocation reading

* add initial support for required forward references in il2cpp types, also fix issues with type names clashing with il2cpp api types

* reduce clang errors for header file, fix better array size struct, emit required forward definitions in header

* expose forward definitions in AppModel, fix issue with method-only used types not being emitted

* remove debug log line

* fix spelling mistakes in gui outputs

* fix il2cpp_array_size_t not being an actual type for later method definitions

* change the default port for new ui dev to 5000

* show current version and hash in new ui footer

* seperate redux ui impl into FrontendCore project

* make inspector version a server api, split up output subtypes and tweak some option names

* add redux CLI based on redux GUI output formats

* replace all Console.WriteLine calls in core inspector with AnsiConsole calls

* add workflow for new cli and add back old gui workflow

* disable aot publish and enable single file for redux cli
