TimeSeries with channel but no name is written to GWF by LALFrame with an empty string name

Writing a TimeSeries to GWF with LALFrame when it has a populated channel but no name results in a FrProcData struct with a name matching the empty string, rather than using the channel name:

>>> from gwpy.timeseries import TimeSeries
>>> a = TimeSeries(range(10), channel="data")
>>> a.write("test.gwf", format="gwf.lalframe")
>>> print(TimeSeries.read("test.gwf", "data"))
