feature windows 32bit support

[foxever]

Is there any reason that only windows 64 bit is supported?

No, but I haven't tested the code on a 32-bit Windows machine.
I'm not sure the memory layouts and alignment requirements are
the same. If you tested it on a 32-bit Windows machine and you
are sure it works, we can remove the build constraint.

I have test 32-bit binary (build on ubuntu 18.04) on windows 10 64-bit and it works fine, I think it should work if remove the build constrain

$ GOOS=windows GOARCH=386 go build -o go-netstat.exe main.go
$ file go-netstat.exe
go-netstat.exe: PE32 executable (console) Intel 80386 (stripped to external PDB), for MS Windows

and it works

❯ .\go-netstat.exe -lis

I tested on windows 11 (change the GOARCH from amd64 to 386), the compilation failed.

\> go env -w GOARCH=386
\> go build -o go-netstat.exe .\test-netstat.go
