validation fails #618
Description
Thank you for developing a shell program with form processing functionality!
The attached file testform.pdf was exported from testform.odt in LibreOffice Writer 7.5.3.2 (latest). The command "pdfcpu form list testform.pdf" returns the following error.
pdfcpu: validateNameEntry: dict=pagesDict entry=Tabs invalid type types.StringLiteral
As a sanity check, I made another file testform2.pdf by adding form fields with Adobe Acrobat Pro 9 (latest version I have). The command "pdfcpu form list testform2.pdf" succeeds. So apparently, the issue is with the PDF file exported from LibreOffice.
OS: Windows 10 Enterprise 22H2 64-bits (19045.2846)
pdfcpu: v0.4.0 dev

I hope this report may be helpful in the development of your code. Let me know if you need any other information or tests. This is the first time I submit a bug (on Github or anywhere) so apologies if this does not follow the intended format.
