• Pass PyPy status to write_pyc.
• Correct packaging pyc-xasm command-line entry.

• Repackage for Python 3.11 and poetry. I can't describe what thrill it gives me to have to do this every few years.
• Correct bug respecting create_code API Fixes #24
• More explicit comments. Add some ## comments. Document module and method information better.
• decode_linotab() is now decode_lineno_tab_old to make it clear that this routine works for versions before 3.10.
• Avoid using asm.code.to_native() for now, since there are bugs.
• Handle numeric labels better.
• Adjust field name co_linetable for bytecode after 3.10.
• Warn if duplicate line numbers are seen and the assembler is before bytecode for 3.10
• Improve EXTENDED_ARG handling and creation.
• If Python bytecode is not set, complain and exit.
• Detect and handle line numbers on instructions
• Add a check for the last instruction being either a RETURN_VALUE, or RERAISE, or RAISE_VARARGS
• Offsets in bytecode for 3.10 need to be divided by two
• Lint code a little

• Adjust to use xdis 6.0.3 or later
• start adding .READ directive

• Fix bugs in cross-assembly bytecode writing
• Detect PyPy.
• Add SIP hash field. Fixes #4

• Fix bugs in writing 3.7 and 3.8 pyc
• Require newer xdis to get fixes to 3.8 pyc marshaling

Still leaves a bit to be desired. (More xdis fixes are needed too). But this is better than 1.0.0.

1.0.0 2019-10-19

• Go over docs.
• Require newer xdis to get early bytecodes bytecodes: 1.0, 1.1, 1.2, and 1.6.
