DeZ80 v3.0.1

This patch release of DeZ80 corrects the order of ignored indexed instruction prefixes when they are chained in an opcode sequence.

For example, the decoded output of the byte sequence DD FD DD FD FD 00 would previously have its ignored_prefixes field incorrectly set to Indexed(IX), Indexed(IX), Indexed(IY), Indexed(IY), Indexed(IY) instead of the correct value Indexed(IX), Indexed(IY), Indexed(IX), Indexed(IY), Indexed(IY).
