Float and Unsigned Int SIO not supported in SIOReader() - [3,4] & [1,1] SIO Headers

[shckltn]

It seems when I try to use sarpy's SIOReader on sio data with types other than complex I run into issues.

I see the following errors when attempting to read in float / real data (4 byte elements) and uint (1 byte elements):

Float 4 bytes [3, 4]

    sioReader = SIOReader(sioFileName)
                ^^^^^^^^^^^^^^^^^^^^^^
  File "c:\Users\username\AppData\Local\Programs\Python\Python311\Lib\site-packages\sarpy\io\complex\sio.py", line 301, in __init__
    sio_details = SIODetails(sio_details)
                  ^^^^^^^^^^^^^^^^^^^^^^^
  File "c:\Users\username\AppData\Local\Programs\Python\Python311\Lib\site-packages\sarpy\io\complex\sio.py", line 75, in __init__
    raise SarpyIOError(_unsupported_pix_size.format(init_head[2:]))
sarpy.io.general.base.SarpyIOError: Got unsupported sio data type/pixel size = `[3 4]`

Unsigned Int 1 byte [1, 1]

    sioReader = SIOReader(sioFileName)
                ^^^^^^^^^^^^^^^^^^^^^^
  File "c:\Users\username\AppData\Local\Programs\Python\Python311\Lib\site-packages\sarpy\io\complex\sio.py", line 301, in __init__
    sio_details = SIODetails(sio_details)
                  ^^^^^^^^^^^^^^^^^^^^^^^

    raise SarpyIOError(_unsupported_pix_size.format(init_head[2:]))
sarpy.io.general.base.SarpyIOError: Got unsupported sio data type/pixel size = `[1 1]`

The sarpy code in question (Link to code):

            # reader basic header - (rows, columns, data_type, pixel_size)?
            init_head = numpy.array(struct.unpack('{}4I'.format(endian), fi.read(16)), dtype=numpy.uint64)
            if not (numpy.all(init_head[2:] == numpy.array([13, 8]))
                    or numpy.all(init_head[2:] == numpy.array([12, 4]))
                    or numpy.all(init_head[2:] == numpy.array([11, 2]))):
                raise SarpyIOError(_unsupported_pix_size.format(init_head[2:]))
            self._head = init_head

As far as I am aware the following is the decoder for the SIO header information:

    SIO_TYPE_U:             1  - Unsigned Integer 
    SIO_TYPE_S:             2  - Signed Integer 
    SIO_TYPE_F:             3  - Float
    SIO_TYPE_CU:            11 - Complex Unsigned Integer (interleaved)
    SIO_TYPE_CS:            12 - Complex Signed Integer (interleaved) 
    SIO_TYPE_CF:            13 - Complex Float (interleaved)
    SIO_TYPE_NU:            21 - Arbitrary Unsigned Type
    SIO_TYPE_NS:            22 - Arbitrary Signed Type

In case this wasn't already known, I just wanted to put it out there. Let me know if I am missing something.

@shckltn Do you have an example dataset you are working with that you can share?
