[feature] Injecting from buffer

[enty8080]

Hi, @kubo

May I ask you if it is possible to inject a shared object library from buffer instead of from the disk. It might be useful when you don't have access to the file system. Moreover, it would be useful if you don't want to write object to disk in order to inject it.

Is it hard to achieve? How can it be done?

Thanks in advance,
