I have a big three channel image data (10000100003 for example) exported as Zarr arrays into three separate folders, fused.zarrfuused_ch_0, fused.zarrfuused_ch_1, and fused.zarrfuused_ch_2, with chunk size of (10001000). Is there a way to read these three channels into ones single Zarr array with chunk size of (10001000*3)?
