Improvement for the Synthetic Bias tutorial

I went through the synthetic bias tutorial (Siril - Synthetic biases) and had some feedback. At some point in the tutorial it mentions this:

If you are getting statistics values as floats, not ADU - depends on your bitdepth preference in Siril - they can be converted to ADU by multiplying by 65535.

I suggest to explain this a bit more. As a newbie I had no idea what ADU is, nor what bitdepth corresponds to floats vs ADU, nor where I set this bitdepth in Siril. I’m guessing you set it in the top right, and 16 bits means floats, 32 bits means ADU.

There is already a slight hint for that later in the tutorial:

The level must be given in ADU (not float, even if you are working in 32b)

But would still be helpful to have that mentioned earlier
