support python 3.8?

[phatpaul]

preprocess.py:49 gives error: AttributeError: 'str' object has no attribute 'removeprefix' Looks like this was added in python 3.9, but I have 3.8.

Since 3.8 is supported in IDF 5.1, I think it should be supported here too.

Thanks. It's a shame that the fix reduces the readability of the code. The first line is self-documenting, the second, not so much.

-  name, _ = os.path.splitext(file.removeprefix('transform-'))
+  name, _ = os.path.splitext(file[10:])

I'm curious if python has something like poly-fills (like in javascript) to prevent having to reduce the code quality to support older VM versions?

Yeah, "monkey patching" is what they call it in Python. Because there is the startswith(...) lines that guard it, I'm okay with the less than elegant solution.
