fix(zfs): Fixed 'Failed to parse value: VariantNotFound' on Linux, zfs-2.0.3

[Candunc]

On Debian 10, zfs-2.0.3-8~bpo10+1, using ZfsOpen3::read_properties() on a pool throws the following error:

thread 'main' panicked at 'Failed to parse value: VariantNotFound', /home/candunc/.cargo/git/checkouts/libzetta-rs-e848604138a482a1/cf5649a/src/zfs/open3.rs:303:56

This is due to my zfs returning bpool normalization formD -, rather than the all-lowercase formd as defined in zfs::properties::Normalization enum. I have modified the enum to catch these camelCase variants.

@Candunc thanks!

@Candunc would you mind pasting raw output from your zfs so i can add a test case for that?
