Getting all options

[hkparker]

Hello, and thank you for all the hard work on gorocksdb!

I'm trying to figure out if there is a way I can dump all options from a database for an API I'm working on.

I see that I can get options by string, which returns an options struct with that string set, so in theory I could call this for every options string. But what I'm looking for is something like this where I can get all options at once. There are a lot of Set* functions on the Options struct, so if there were corresponding Get* functions I could build something from that as well, but again a "get all" function would be easier.

I'm thinking I could probably create a PR based off this, but I'm not very familiar with cgo, so before I go down that route I figured I should ask if there is already a way to do this that I'm missing.

Thanks.
