nvcompBatchedZstdCompressGetTempSizeAsync returns monstrous temp buffer sizes

[proc-sim]

[reposting here because I originally missed the instruction in the legacy nvcomp repo to post issues here instead]

nvcompBatchedZstdCompressGetTempSizeAsync returns giant values for temp_bytes, no matter the size of the input data. Even if only 4 bytes are being compressed, the temp buffer size returned will be around 500mb.

Surely a temp buffer of that size isn't actually required for such a small chunk of data to compress?

Ex: this returns a comp_temp_bytes value of roughly 540mb, despite only compressing 4 bytes:

    size_t comp_temp_bytes;
    status = nvcompBatchedZstdCompressGetTempSizeAsync(1, 4, nvcompBatchedZstdOpts, &comp_temp_bytes, 1 * 4);
