Fixed plot_every_cycle
Added port dimensions to overlay of injection port; added DD chamber to CV polygons
Updated analysis of discharge port blockage; especially for compressors where port opens before discharge angle; Moved updated injection code into base class
Removed HDF5 plugin (didn't do anything anyway)
Updated default config for injection
Removed ABC for pdsim_plugins; seems broken :(
