Multidimensional Coord

[alexhad6]

In Xarray, coordinates can be multidimensional. However, the Coord object currently cannot specify multiple dimensions and therefore requires a multidimensional array.

Solution: Keep the default behavior of Coord (to be 1D and have the name automatically be the dimension), but add the ability to specify multiple dimensions separately from the name.

Example from Mo:

from datalogs import Logger, Coord, DataVar
import numpy as np

node_logger = Logger("logs")
time = np.linspace(0, 100, 11)
voltage = np.linspace(0, 10, 21)
times, voltages = np.meshgrid(time, voltage)
signal = np.cos(2*np.pi*voltages*times/200)
node_logger.log_data(
    "q1_spec_signal",
    [Coord("x", data=times, long_name="Time", units="s"), Coord("y", data = voltages, long_name = "Voltage", units = "V")],
    [DataVar("signal", dims=("x","y"), data=signal, long_name="Signal", units="a.u.")],
)
