In Windows Server 2025 the ESE pagesize increased to 32kb. The AvailablePageTag field is therefore reduced to only 12 bits with the rest of the bits used for something else. This caused this library to break in parsing the pages and crash. This PR also adds some more resilience in parsing corrupted data to avoid some crashes.
