 Currently only the `plot` module is included.
 
-### convert.py
-
-- Made the `pcbdraw` import relative
-- Removed PIL as dependency
-  - So now the save function only supports SVG as input and SVG/PNG as output
-  - All other cases are handled from outside
-  - This is because KiBot heavily uses ImageMagick and migrating to PIL is not something simple
-  - There is no point in using PIL just for file conversion, as we don't use `render` this is the only use

 - Removed the command line interface, just because it pulls click
 - Added `create_renderer`. Just creates the correct MD/HTML mistune renderer
 - Made `mdrenderer` import relative. So we get the mdrenderer from the same dir, not the system

+- Replicated find_data_file (from plot.py) to avoid cross dependencies
