Splitting a multi-page PDF can result in incorrect behaviour #73
Description
When placing pages of a multi-page PDF, if you place a second PDF between the pages, you do not see the second PDF. To illustrate this, I have created 2 PDFs; 2page.pdf and extra.pdf (attached). If I import page 1 of 2page.pdf, then import extra.pdf and then import page 2 of 2page.pdf, I would expect to get the output shown in the attached expected.pdf. However, I actually get the output shown in attached output.pdf. I am using fpdf (https://codeberg.org/go-pdf/fpdf) version v0.11.1 with v1.0.15 of gofpdi.
