When generating the plugin loading functions from protobufs, previously there was only an option to load plugins directly from disk via file names. This prevents use cases such as loading plugins embedded using `embed` or via an `fs.FS` virtual filesystem. To address this, there is now a `LoadReader` method generated that accepts an `io.Reader` and uses that via `io.ReadAll`, rather than having to load a file via `os.ReadFile` first. The existing `Load` method has been rewritten to simply call `LoadReader` with the result of calling the `os.Open` with the file name.

I haven't tested it myself, but if someone else has tested it and confirmed that it works, the change seems fine. |
Ok, let's keep it in PR, I'll do testing today. |

Description of changes:
I ended up writing this for my own use before I noticed that there was an existing PR/Issue for this already. Since the other one still hasn't been merged, I figured I may as well throw my hat in the ring as well. By sheer coincidence it's almost identical to the other PR, except for the following:
