Mimosa26 automatic threshold tuning and column masking

[laborleben]

• Global threshold tuning (register IVDREF2)
• Quarter threshold tuning (registers IVDREF1A/B/C/D)
• Noisy column masking (register DisableLatch)
• Edit default configuration files and remove any ANEMONE specific changes (e.g., masked columns, individual thresholds)

[themperek]

BTW: configuration files can be just limited to those 4-5 things (per frame) that are changing.

Thanks for opening this issue. ;)
We should also 'tune' global and quarter threshold using a allowed limit on noise data (or noise hits) per second. And maybe if this does not help we can do mask some noisy columns. But this we can discuss in detail.

[laborleben]

Maybe we add a standard config file where we set the threshold to 255 (or whatever is the maximum) and which we load from beginning and afterwards just write the threshold values and other important registers using the set_configuration() method provided by basil.

[YannickDieter]

Yes, 255 is max. Good idea, then we can use this as a starting point for the tuning, a modify this, load it and then scan,.. and so on.

Upto now only the local registers IVDREF1A/B/C/D are tuned. Global threshold is not touched and no noisy pixel masking is implemented. See PR #19.
