Compile a binary shellcode blob into an exe file

As a malware researcher I do this mostly for shellcode debugging. Some researchers use "shellcode_launcher", but it's easier to convert the shellcode to exe because it allows doing both static and dynamic analysis in IDA Pro.

The executable is created in 2 steps:

1. An assembly source file is created with an "incbin" directive
2. The assembly file is assembled with yasm into a .obj file
3. The .obj file is linked into a .exe file
4. The .obj and .asm files are removed

Required Arguments:
- architecture: 32 or 64 (depending on the shellcode)
- shellcode blob file name
- Output executable file name
