5863cd10b8 Fix possible null pointer dereference 
It's possible that if the FILE passed to yy_create_buffer is at the
end-of file, there may be a null pointer dereference.

This should hopefully fix that.

Found with clang-tools' scan-build:

src/asm/lexer.c:281:25: warning: Array access (via field 'pBuffer')
 results in a null pointer dereference
        pBuffer->pBuffer[size] = 0;
                 ~~~~~~~       ^
1 warning generated.

db1eb8fbcb Revert "Prevent RGBASM from outputting corrupted files" 
This reverts commit 06fe27c516.

According to Microsoft's documentation
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/tmpfile?view=vs-2019
`tmpfile` attempts to create the temporary file at the **root** folder
This seems to assume that the user has admin rights; might be a compat
thing, idk, but it breaks on people's computers.
(CI didn't catch it, annoyingly.)

Reverting to make RGBASM usable on most Windows computers.
(Sanely-configured ones, at least.)
Another solution to #446 needs to be figured out, yay...

cb52ae0f26 Implement unionized sections in RGBASM 
This touched a lot more code than initially expected, for two reasons.

First, this broke a big RGBASM assumption: that sections are always being
written to at their end. This plus other problems required touching
basically the entirety of `section.c`.

Second, I tried different solutions to solve the above problem, and along
the way I cleaned up many things around. (I believe that keeping this to
"cleanup" commits yields subpar results, and since it's boring they get
postponed anyways.)

RGBLINK support still needs to be added, but this will come next.
