Missing empty segments for parquet read of segarray with string values

[stress-tess]

Encountered while working #2539 and trying to extend testing of test_segarray_write to cover string values

In [5]: a, b, c = ["one", "two", "three"], ["un", "deux", "trois"], ["uno", "dos", "tres"]

In [6]: s = ak.SegArray(ak.array([0, 0, len(a), len(a), len(a), len(a) + len(c)]), ak.array(a + c))

In [7]: s
Out[7]:
SegArray([
[]
['one', 'two', 'three']
[]
[]
['uno', 'dos', 'tres']
[]
])

In [8]: s.to_parquet("segarray_test_empty")
Out[8]: 'Dataset written successfully!'

In [9]: rd_data = ak.read_parquet("segarray_test_empty*")

In [10]: rd_data
Out[10]:
SegArray([
['one', 'two', 'three']
['uno', 'dos', 'tres']
])

@pierce314159 - is this with single locale or multiple? I definitely remember this working so I want to make sure I am not missing anything.

EDIT
I was able to reproduce this on single locale. I am also going to be testing on multi-locale, but will need to do so later.
