As mentioned here #2637 (comment) , this transform helps to fix NaN values after the input transforms.
It is basically only a wrapper around SignalFillEmpty.

looks good to me, please add a unit test following the existing one https://github.com/Project-MONAI/MONAI/blob/dev/tests/test_signal_fillempty.py

not sure if replacement should allow for different inputs for different items in the keys, I guess we can expand the logic later if needed.

@wyli Sweet, thanks! I'll go add the tests and add it to the symbol table.

Also I realized the array test is broken: https://github.com/Project-MONAI/MONAI/blob/dev/tests/test_signal_fillempty.py#L27C1-L36C1

self.assertTrue(not np.isnan(fillemptysignal.any())) always evaluates to True if there is any non-zero value in the array. Can I fix that in this commit as well or do you want a separate one?
The fix is simple self.assertTrue(not np.isnan(fillemptysignal).any())

Related to #7011. I was using the `Signalfillemptyd` (based on
`Signalfillempty`) transform in monailabel and found out, it currently
allows no inversion.
When digging deeper I realized that SignalFillEmpty just throws away the
meta information.
With the simple addition of `track_meta=True` it works as expected.
I hope it has no other impact, but I honestly don't know.

@wyli would be cool if we can add this to MONAI 1.3.0, thanks! I can
also rework `Signalfillempty` to just accept any datatype, if that would
the more appropriate approach.
