[BUG] GetAttachedFiles causes panic

[crashingfish]

Description

GetAttachedFiles was introduced in 3.5. Calling it on a pdf file with attachment consistently causes panic.

Expected Behavior

Return a list of attachments if any.

Actual Behavior

Steps to reproduce the behavior:

1. Read a pdf file with attachments
2. Call GetAttachedFiles to test.

Sample code

`
fileBytes, _ := os.ReadFile(filename)

pdfReader, err := model.NewPdfReader(bytes.NewReader(fileBytes))

attachments, err := pdfReader.GetAttachedFiles()
`

Attachments

Cannot share internal pdf file due to compliance issues. However the code was testing against loads of files and the issue is consistent.
