fix: lerc is not lossy unless max_z_error is > 0 #88

Closed blacha closed 8 months ago

blacha commented 8 months ago

When using GDAL with LERC it will default to lossless, unless max_z_error is greater than 0

Also lossless LERC works surprisingly well for non floating point types (eg 8bit RGBA or 16bit RGBi)
