Invalid file error on reading a sas7bdat file created by vers7, win 95

[stefanverbeeck]

Describe the issue
We are getting exceptions when trying to load the following file sas7bdat file:
dummy_file.zip

Exception:

data_frame, metadata = parser_entry_point(
                           ^^^^^^^^^^^^^^^^^^^
  File "pyreadstat/_readstat_parser.pyx", line 1411, in pyreadstat._readstat_parser.parser_entry_point
    data_frame, metadata = run_conversion(filename_path, file_format, file_extension, encoding, metaonly,

    raise ReadstatError(err_message)
pyreadstat._readstat_parser.ReadstatError: Invalid file, or file has unsupported features

We don't know why this one specifically fails.
It is noted, that the header lists this as being made by SAS version 7; on windows 95 32 bit.
(The actual file is generated by new procedures, it's just an old file that new data is being append too).

To Reproduce

import pyreadstat as ps
path = "dummy_file.sas7bdat"
df, meta = ps.read_sas7bdat(path)

Setup Information:
tried on various pyreadstat versions;
All installed via pip; running on windows 11 64bit, running on plain python 3.12 in a virtualenv.
