0.1.12 regression: `PdfDocument.TryGetForm` doesn't find any forms

[cremor]

I found a regression in version 0.1.12. It seems like PdfDocument.TryGetForm never finds any forms (at least with the files that I tested).

Sample input files:
Input visible.pdf
Input invisible.pdf
(Note: I know that the digital signatures of those files are invalid. This is because they are only test signatures. They should be found anyway.)

Sample code:

using var pdf = PdfDocument.Open(InputFile);

if (!pdf.TryGetForm(out AcroForm form))
{
    Console.WriteLine("ERROR: No AcroForm found");
    return;
}

var signatureFields = form
   .Fields
   .Where(x => x.FieldType == AcroFieldType.Signature)
   .ToArray();

if (signatureFields.Length == 0)
{
    Console.WriteLine("ERROR: No Signature field found");
    return;
}

foreach (var field in signatureFields)
{
    Console.WriteLine("Signature field found: " + field.Information.PartialName);
}

Expected output:
Signature field found: Signature1

Actual output:
ERROR: No AcroForm found

@cremor can you confirm you were previously using v0.1.11? And not any pre-release?

[cremor]

Yes, I updated from release 0.1.11 to release 0.1.12 and then I noticed the bug.

@cremor this is now fix and will be available overnight in the pre-release version.

I'm planning to do a new full release 2 to 3 weeks from now. Please continue to report regression if you find some.

Thanks again for your help!
