XArray accessor

[ahuang11]

Would be nice to monkeypatch / have an xarray accessor on import:

1. to_xql

import xarray as xr
import xarray_sql as xql

ds = xr.tutorial.open_dataset("air_temperature")
ds["air_x2"] = ds["air"] * 2
ds.to_xql("era5")
# create table air and air_x2

2. or directly call xql with accessor https://tutorial.xarray.dev/advanced/accessors/01_accessor_examples.html?

import xarray as xr
import xarray_sql as xql

ds = xr.tutorial.open_dataset("air_temperature")
ds.xql.execute("SELECT * FROM air")

I really like this idea
