Description

Currently, the only way to reclassify rasters in QGIS (through the Processing Toolbox) is with r.reclass or r.recode. r.reclass only allows for an input text file with set numbers as intervals, which isn't optimal if an automated reclassification is desired based on data distribution.

r.quant or r.quantiles also exists, but neither actually apply the quantiles for the raster to a new dataset.

It would be ideal if this could be integrated into QGIS/GRASS as a tool in the processing toolbox so that automation can be achieved through the modeler, possibly with different reclassification methods (quantiles, equal intervals, natural breaks, etc). These can be done in the symbology properties, but it would be good to be able to create a new raster with these values baked in.
