consider using window/logMessage instead of console logging

[WhoIsSethDaniel]

I was wondering if, instead of writing certain things to stderr (certain .pl file's output is written to stderr, maybe other stuff), PerlNavigator could use window/logMessage?

At least in Neovim it allows a user to intercept the contents of the message and do something interesting with it. By default it just causes Neovim to log to the lsp.log, but if you have something like output-panel installed it means the user can see these messages in a buffer from within Neovim. I had no idea of this feature until I installed this plugin and used gopls which spits out all sorts of interesting info that I was unaware of (since I rarely look at the lsp.log and there are a lot of things going on in that log).

FWIW, the current writing to stderr does cause Neovim to write to the lsp.log. The difference is that there does not seem to be a way to intercept this like can be done with window/logMessage.
