getCreationDate has issues parsing some dates

[saul-prepared]

What were you trying to do?

Trying to get the creation date of a PDF. The PDF has a creation date of D:20210514143134-5'00'

How did you attempt to do it?

Call the getCreationDate function.

const data = new Uint8Array(doc.Body as Buffer);
const pdfDoc = await PDFDocument.load(data, {
updateMetadata: false
})
let originalCreateDate = moment(pdfDoc.getCreationDate()).utc().toDate();

What actually happened?

It throws the following error "Attempted to convert "D:20210514143134-5'00'" to a date, but it does not match the PDF date string format."

What did you expect to happen?

Expected it to return a date.

How can we reproduce the issue?

Here is the link to the JS fiddle https://jsfiddle.net/3fu4vj2c/1/
The example is the copied and pasted parseDate function.
I cannot provide the pdf file that caused the issue because it is a legal document that cannot be shared.

The JS Fiddle has a suggested fix as well.
