This is a port of z2dmp which was originally written in C++. As we are moving to a more cross platform and interoperable architecture, this has been rewritten in Rust.
.zdmp files are compressed Microsoft full memory crash dump files generated by DumpIt driver. The compression layer is our own flavor which is why it is open-source.
The reason for a simple format is because it is handle by DumpIt kernel driver.
