Clustering4D: updated README

**Status**: Functional
### Description
This module performs clustering for detectors with valid individual hit timestamps. The clustering method is either an arithmetic mean or a a charge-weighted centre of gravity calculation, using a positional cut and a timing cut on proximity. If the pixel information is binary (i.e. no valid charge-equivalent information is available), the arithmetic mean is calculated for the position. Also, if one pixel of a cluster has charge zero, the arithmetic mean is calculated even if charge-weighting is selected.
This module performs clustering for detectors with valid individual hit timestamps.
The clustering method is either an arithmetic mean or a a charge-weighted centre-of-gravity calculation, using a positional cut and a timing cut on proximity.
If the pixel information is binary (i.e. no valid charge-equivalent information is available), the arithmetic mean is calculated for the position.
Also, if one pixel of a cluster has charge zero, the arithmetic mean is calculated even if charge-weighting is selected because it is assumed that the zero-reading is false and does not to represent a low charge but an unknown value.
Thus, the arithmetic mean is safer.
Split clusters can be recovered using a larger search radius for neighbouring pixels.
