	def _tile_read(
	src_dst,
	bounds,
	tilesize,
	indexes=None,
	nodata=None,
	resampling_method="bilinear",
	tile_edge_padding=2,
	dst_crs=CRS({"init": "EPSG:3857"}),
	bounds_crs=None,
	minimum_tile_cover=None,
	warp_vrt_option={},
	):

we pass the output array size with tilesize, this means the output array will be a square shape (tilesize, tilesize). By allowing (height, width) we could use _tile_read to return any part of a dataset given any bounds (square or not)

This is a breacking change for a private function.
