URL: https://github.com/apache/arrow/issues/37996
### Describe the enhancement requested
Right now, the only way to construct an `arrow.array.StructArray` is to call
its static method `fromArrays` method. Doing so requires users to first
construct the individual field arrays before creating the `StructArray`.
```matlab
>> a1 = arrow.array([1 2 3 4]);
>> a2 = arrow.array(["A" "B" "C" "D"]);
>> s1 = arrow.array.StructArray.fromArrays(a1, a2, FieldNames=["Number"
"String"])
s1 =
-- is_valid: all not null
-- child 0 type: double
[
1,
2,
3,
4
]
-- child 1 type: string
[
"A",
"B",
"C",
"D"
]
```
It would be nice if users could construct `StructArray`s from MATLAB
`table`s:
```matlab
>> t = table([1 2 3 4]', ["A1" "A2" "A3" "A4"]', VariableNames=["Number",
"String"])
>> s1 = arrow.array.StructArray.fromMATLAB(t)
s1 =
-- is_valid: all not null
-- child 0 type: double
[
1,
2,
3,
4
]
-- child 1 type: string
[
"A",
"B",
"C",
"D"
]
```
Adding `fromMATLAB` to `StructArray` enables returning `StructArray`s from
`arrow.array()`:
```matlab
>> t = table([1 2 3 4]', ["A1" "A2" "A3" "A4"]', VariableNames=["Number",
"String"])
>> s1 = arrow.array(t)
s1 =
-- is_valid: all not null
-- child 0 type: double
[
1,
2,
3,
4
]
-- child 1 type: string
[
"A",
"B",
"C",
"D"
]
```
