Dialyzer API changes

Dialyzer changed it's API in OTP 26, and as a result, I'm unable to generate the PLT from my app.
The problem is that I was using the dialyzer_cl_parse:get_lib_dir/1 function to get the directory of some basic libraries to analyze for the PLT, but its now moved to a different module, and not exported anymore.

Solutions I could think of were to either hardcode the folders, which I would rather not do, or require the user to create a dialyzer config file, that contains these apps, which I think is also not too ideal.

For the time being, I turned off automatic PLT generation, so I have to do that by hand.
