I fixed a few things here. I can open a new PR, too.

[driftregion]

@danielhrisca would it be possible to stream to a file directly?
Also: i accessed a private attribute to get the current file size, is there a better way to do that?

@danielhrisca would it be possible to stream to a file directly?

The only way to stream to the file is to use the extend method, but this is performance bottleneck for high data rates.

Also: i accessed a private attribute to get the current file size, is there a better way to do that?
I don't think so. Why do you need that information?

[zariiii9003]

@danielhrisca
The SizedRotatingLogger starts a new file when a give file size is reached. That's why i added the file_size function to the logger classes.

The BlfWriter compresses and writes data in chunks so maybe that could be possible here too?

I'm going to remove the platform and python version requirements unless there is a good reason not to?

[zariiii9003]

I think i added this so CI does not fail on PyPy and CPython 3.11. But there's probably a better solution for that. I admit this is ugly.

[hardbyte]

Why is that?

[zariiii9003]

It's a limitation of asammdf. See here
