What's changed from v1.3.5 to v1.4.1

Too many versions in between. Check the following for details.

https://github.com/pocketpy/pocketpy/releases/tag/v1.3.6
https://github.com/pocketpy/pocketpy/releases/tag/v1.3.7
https://github.com/pocketpy/pocketpy/releases/tag/v1.3.8

https://github.com/pocketpy/pocketpy/releases/tag/v1.4.0
https://github.com/pocketpy/pocketpy/releases/tag/v1.4.1

The most important changes

1. str was changed to be null-terminated. So python.c was altered for new string ops
2. allow const tuple as function default parameter. e.g. def f(a=(1,2)): ...
3. add array2d module. An efficient general purpose 2d array
4. add full support about @staticmethod and @classmethod
5. add full slice support. e.g. a[:, 1:2:3]
6. add support for try..finally
7. add complex number support and cmath module. For example, 1+2j
8. support real exception objects. Now you can define a class derived from Exception
9. add line_profiler module. See this page for details

Notes

target_compile_definitions(pocketpy PRIVATE PK_ENABLE_OS=0) was removed because currently PK_ENABLE_OS defaults to 0.
