Validation error for nans in TimeSeries/T3D/etc missing

[veenstrajelmer]

Describe the bug
When writing a TimeSeries (or ForcingModel) containing nans, there is no validation error. However, the FM kernel is not able to handle nan values and it will crash with some erro. Therefore, nans in the file are not valid FM input, so should be validated by hydrolib-core.

To Reproduce

from pathlib import Path
import numpy as np
import hydrolib.core.dflowfm as hcdfm

datablock = np.random.uniform(low=-40, high=130.3, size=(4,2))*np.nan
datablock_list = datablock.tolist()

steric = hcdfm.TimeSeries(
    name="east2_0001",
    quantityunitpair=[hcdfm.QuantityUnitPair(quantity="time", unit="seconds since 2022-01-01 00:00:00 +00:00"),
                      hcdfm.QuantityUnitPair(quantity="waterlevel", unit="m")],
    timeinterpolation=hcdfm.TimeInterpolation.linear,
    datablock=datablock_list, 
    )
bc_east = hcdfm.ForcingModel()
bc_east.forcing.append(steric)
bc_east.save(filepath=Path("./steric_east2_hydrolib.bc"))

Expected behavior
Error when nans in dataset.

• Version 0.3.1 (main branch of today)

Discussed this issue with @arthurvd. Even though we know the requested change should be applied to more FM files, for now we will only fix the NaN validation in datablocks. We can create separate issues for the other files/locations.
