fix: Segfault when hashing regions spanning multiple MiBs (#1804)

Browse Source 
### Problem description

Attempting to do an MD5 hash of a large region (e.g. 2 MiB, ``u8
data[0x200000]``) crashes with a segfault.

### Implementation description

In ``hex::plugin::hashes::hashProviderRegionWithHashLib()``,
``hashFunction->TransformBytes()`` is called with an offset of 0,
because it iterates over ``data`` and not the entire region.
