Renamed python script so that it sits next to the testbench file when alphabetically sorted.
Reverted `MAX_WIDTH` to full precision for truncation testing.
Expected values are now stored in full precision rather than truncating to the same value as the input.
i.e. 0x5a5a5a5a will truncate to 0x5a5a for write data but will remain 0x5a5a5a5a for expected read.
Adds TDP submodule to generator.
Adds shorthand expected signal to testbench (mostly to make it easier when I look at the vcd dump to figure out what I did wrong in tests).
