Check for required language server functionality.

[dsully]

If a language server doesn't support functionality required by lps-lens.nvim many errors are emitted:

method textDocument/references is not supported by any of the servers registered for the current buffer

repeatedly.

I see that this function exists:

local function lsp_support_method(buf, method)
  for _, client in pairs(lsp.get_active_clients({ bufnr = buf })) do
    if client.supports_method(method) then
      return true
    end
  end
  return false
end

But isn't called for every client request. This will fix it:

Should fix now, reopen if you re-encounter the bug. :)
