From the commit message:
The reader class reads one event at a time from a RAW file. The reader is able to automatically detect if the file is uncompressed or ZSTD compressed. In the later case, it is decompressed on the fly.
One step of many in #200 (closed).
How Has This Been Tested?
Test files can be read and unpacked by a modified version of !261 (merged). The end-of-file conditions is properly handled.
