I have realized that delta does not necessarily has to be constant
throughout map->reduce stages. I added delta as options to tdigest_reduce and
tdigest_quantile kernels and changes type to list<double not null>. Now
tdigest centroid structs is as follows:
```
struct_({
field("mean", list(field("item", float64(), false)), false),
field("weight", list(field("item", float64(), false)), false),
field("min", float64(), true),
field("max", float64(), true),
field("count", uint64(), false),
})
```
