Revert "Update the OpenMcdf library in vbad project"

[m-kovac]

In OpenMcdf 3.x, CfbStream buffers writes and defers updating the directory entry metadata until the stream is disposed/closed. This wasn't done and the produced compound files are corrupted - the stream/directory entries metadata are not updated and the entries appear to be empty although the data were written and the file has correct size. Reverting for now.

Next steps:

1. Round-trip tests that will compile and then decompile the compound file to check if the stream/directory entries correspond with the data written.
2. Eventually update to OpenMcdf 3.x and update the code to explicitly dispose the streams.
