How to specify the compression level?

[purew]

I don't see any way of specifying the compression level in the encoder?

Another rust library allows specifying this as the level config

    // 0 == default (fast mode); values above 16 count as 16; values below 0 count as 0
    level: u32,

How can I specify this in lz4_flex?

Compression level woud be via hc mode, which is not implemented currently. hc mode would be much slower though
