Refactor/Overhaul (#40)

* major refactor/overhaul
move generation implementation to libumskt/*
decouple CLI/Options (and JSON) from generation implementation
set groundwork for future shared library
use standardized PIDGEN2/PIDGEN3 naming convention
create a Windows Docker file for quick compilation
add Windows resouce file/header so we have an application icon on windows
use icon from @Endermanch (used with permission)
add support for fully-static linux/muslc-based compilation
add support for a dos/windows (i486+) binary using djgpp
add Dockerfile to compile gcc/djgpp/watt32/openssl to provide DOS (DPMI) binaries
add @Endermanch 's Vista+ documentation
update Readme for recent credits

* begin work on C linkage and emscripten buildpath

* Update CMake to include and build Crypto++

* move dllmain.cpp to the correct directory

* add rust port info to README.md

* re-add dropped changes from rebase

* update build config, specify windows XP version number for crypto++

* update dos-djgpp action to use new cmake builder and options

* update dos-djgpp to use UMSKT hosted forks

* update other workflows to include standard header

* remove crypto++ from build config for now

* use the new `shell` parameter in `threeal/cmake-action`
TODO: move to a stable version (v1.3.0) when ready

* use full commit hash because a shortened hash is unsupported

* add the required {0} parameter?

* add openssl 3.1.1 to windows github runners

* ensure linux matrix build compiles on the correct arch
