handle new record in new vbaproject.bin if present

[beauvankirk]

In one of the recent updates to the MS-OVBA Office VBA File Format Structure specs, a new 10-byte CompatVersionRecord block was added to the PROJECTINFORMATION block:

The record is identified with id 0x004A:

The insertion of this new record leads to corrupt/failed parsing of the remainder of the PROJECTINFORMATION record. For my use case this was the source of this issue: #811.

Adding a conditional check to skip over this new 10-byte record if encountered resolved the issue for me. This is a pretty targeted/brittle solution...I'm not sure if there is a more robust route (this was my first time actually diving into the file format).

Apologies, I searched for prior issues, hence linking #811, and I thought PRs as well but I missed that preexisting PR.

I reviewed #723 and this one and I suggest merging the other one as it includes test data and actually parses the record. Just needs a rebase onto main
