Use data type information from headers provided by the user

[PeterMatula]

We should make it possible to pass headers to RetDec that will be used to extract information about function data types. Then these types would be applied to functions during decompilation.

Original email from user:
I have a dll and accompanying header file that I want to decompile. I cannot see how to feed the header file into the decompilation process and without the header file, the decompiled export functions have (void) argument list, which is incorrect of course. In fact, I see that all the internal functions also have (void) argument list. This seems wrong too.

I also think this future is critical for normal output results.
Are there any update or forecast when this will be added?
I think this can make the change we looking for and finally put us in ida_hex_ray level and better then this...

Hi @eagleFromHeaven. Unfortunately, we do not have any estimates. This feature does not represent a priority for us, so any help would be appreciated.
