Missing pack/unpack methods

[MDr164]

This library is currently only intended as a client so I can see why request types only have a Pack() method and responses only got an Unpack() method. I intend to use this library for an IPMI server instead so I'd need both methods on such types. Would you accept a PR that adds the missing methods or is that something you'd rather not have in this library directly?

The idea of using this library as server is very appealing, I am very willing to accept the PR that implement these things.

And I think It is not so urgent to implement the actual working code for Unpack()/Pack() for all those existing Request/Response types. They can be supplemented one by one. :)

Cool, I'll implement those methods then and open some PRs. I envision that I'll have to do minor refactoring by separating some client functions into their own files for readability but so far I got quite far by implementing the missing functions locally. I did however notice that some that some structs could be packed differently so simplify some Pack/Unpack methods.

Btw I picked this issue back up after some time and I'm currently experimenting with it here: https://github.com/MDr164/go-ipmi/tree/ipmi-server but it turned out I had to restructure quite a bit to make it work cleanly. I was also thinking about creating an API compatible change but that would have required a lot of compromises on the server-side code. I'm running some more tests here in the next couple days before opening any PR, especially around API compatibility with the current library.
