Empty diagnostics

Issue details

Hello,
I am trying to set up hdl_checker in neovim with coc.nvim, but have a big problem with error highlighting - there is none. At first , with the start of nvim, hdl_checker works fine and creates "_hdl_checker" default directory and parses all HDL files. But upon opening any of them I see neither the "bar" with typical ">>" symbols indicating an error no any other highlights.

Upon closer inspection of hdl_checker temporary log files, i noticed that all "diagnostics" fields in the packets sent to coc.nvim are empty:

INFO    | 18:32:38 | hdl_checker.core @ getMessagesWithText():544 Thread-122 |	Getting messages for 'c:\logger\hdl\logger.v' with content
INFO    | 18:32:38 | hdl_checker.database @ _updatePathLibrary():353 Thread-122 |	Setting library for 'C:\Users\Nikita\AppData\Local\Temp\nvim.0\xG65Fc\tmp2qh7mvgg.v' to 'not_in_project'

INFO    | 18:32:39 | hdl_checker.builders.fallback @ build():428 Thread-150 |	Forcing build of c:\logger\hdl\logger.v

So essentially coc.nvim never gets any info about errors in the analyzed files and naturally doesn't draw anything. But the hdl_checker does get all the information about any changes to a file. In this example I purposefully added a couple of errors into the "logger.v" file, but the "diagnostics" were still empty.

What may be the cause of this problem?
Please help!

• hdl_checker -V : 0.7.4
• python --version : Python 3.8.10
• OS: Windows 11 Pro, 10.0.22631 Build 22631
• nvim : v0.9.2
• vsim -version : Model Technology ModelSim ALTERA vsim 10.1e Simulator 2013.06 Jun 12 2013
• Can't find a way to get my coc.nvim version, but I installed it with vim-plug so it should be one of the latest.
