Adds functionality to delete bad models. Models are batched together and deleted in one commit.
More testing is needed to ensure data safety. Positive tests on a live database reveal the broken models were truncated and complete ones were kept around successfully. Tests should be done to ensure larger sd0 models are properly saved and not truncated since this command should be able to be run any time.
Valgrind tests need to be run as well to ensure no memory leaks exist.
Add brick by brick conversion commands with 2 parameters to tell the program what to do with the data.
Add zlib -> sd0 conversion. Files look good at a glance but should be tested in game to ensure stability. Tests to come.
