support codelens action beside reference

[KevinNitroG]

hi author @oribarilan, I don't really know much about these stuff. Recently I have discovered the codelens and what does it mean. I enable for golang, and it is nice with builtin vim.lsp.codelens.enable(true) (I don't know how it is called, I guess "action"?)

but, seem that lensline doesn't show anything for this? lensline virtual text format is very nice. It would be awesome that lensline support this

Maybe relate #43 I guess...?

Hey @KevinNitroG . Do you have any thoughts on how the lsp codelense feature can play together with lensline? How do you imagine lensline supporting this?
I would love some ideas, since I am not using the built-in codelense feature myself.
Thanks!

The biggest issue I see is that lensline puts things at the start of functions. It doesn't currently have any way for a provider to indicate that it should be putting something elsewhere.

But codelenses are often other places, and the tools for executing codelenses depend on the cursor being where the lens is.

@oribarilan Thoughts on if this is something that we want to support?
