v1.1.0: C standard mode performance improvements

[hit9]

• Improve C bitprotolib performance BpCopyBufferBits
• Fix bitproto compiler python error for __post_init__ function
• Improve C bitprotolib performance array of byte; uint8/16/32/64; int8/16/32/64 and enum, alias of them
• Add a more complex unittest case for encoding/decoding correctness.
• Add one unittest case on stm32 board.

target v1.1.0 before 2023/01/15.
