Wavecrash - fixed crash in wavelet specially when using "edge sharpening" (#5854)

Browse Source 
* Add epsil to all log calculation

* add another epsil to log

* Another eps value in koeli calculation

* Avoid negative L values after reconstruct

* Suppress all changes except negatives values reconstruct
