* simplify SizedBytes and StructStream * lint * super() !!! * do not pass parameter up to super().__init__() * Update chia/util/struct_stream.py Co-authored-by: Arvid Norberg <arvid@libtorrent.org> * parse fixed-width int data from class name * add int512 and uint128 .from_bytes(), test .parse() failures * test serialization against struct.pack() * use typing_extensions for final * override ignore * stop using struct for StructStream oh the irony * fixup .to_bytes() to accept parameters again for where we use that * bring back signed parameter * format * adjust tests for new exception * eliminate custom coding for uint128 and int512 * tidy * remove unused StructStream.PACK attribute * add direct tests for parse_metadata_from_name() * stricter hinting * remove no-longer-needed typeshed work-around * apply strict type checking to all touched files * remove StructStream override of .to_bytes() * tidy * types touchup * add unused parameter comments Co-authored-by: Arvid Norberg <arvid@libtorrent.org> Co-authored-by: wjblanke <wjb98672@gmail.com>
