Pull request overview
Consolidates iOS SHA-256 hashing into a reusable utility and reduces memory usage through chunked file reads.
Changes:
- Adds shared data and file hashing functions.
- Migrates update-manifest hashing to the utility.

Split off from #48. We'll be doing more SHA-256 checksumming in additional codepaths, let's extract this to a common utility.
As a bonus, some existing callers, which loaded entire files into memory before hashing are now loading data in smaller chunks.
