🗒️ Description

Translate Ori's eof example tests into .py

while working on the tests I realized 3 breaking changes

• opcode JUMPF is 0xe5 not b1 as we had
• opcode JUMPV first length byte is len(args) - 1, c++ style
• and a few tweaking flags to the Container.Code section auto calculation in eof bytes
