BUG/MINOR: compression: Add OOM check for calloc() in parse_compression_options()

Browse Source 
This patch adds a missing out-of-memory (OOM) check after
the call to `calloc()` in `parse_compression_options()`. If
memory allocation fails, an error message is set, the function
returns -1, and parsing is aborted to ensure safe handling
of low-memory conditions.
