Add support for .pde sketch extension (#59)

Previously, only sketches that use the .ino file extension were recognized.

There are still popular libraries and sketches that use the .pde extension, which are either unmaintained or with maintainers who have no interest in changing the extension, so support for .pde is required for this action to be a general purpose tool for compilation testing of all Arduino projects.
