Prefer Uint8Array as internal representation of binary data

[jimhark]

Summary

Use Uint8Array to store binary data. This is a major refactor based on number of lines, but low in complexity, most of the changes are almost mechanical.

Resolves

Resolves #215, #216, #217, #218

Details

• The big change is to prefer Uint8Array for holding binary data
• Hex strings are converted to Uint8Array on input
• Uint8Aarray is converted hex strings for output where needed
• API calls that accept binary data no longer need conversion from hex strings
• For large files, memory use is greatly reduced
• For large files, speed in noticeably improved

Testing

I manually tested node encrypt, node decrypt, and HTML wrapper decrypt.

Notes for Reviewers

The scope should have been limited strictly to the switch from hex strings to Uint8Array, but I included other changes related to memory reduction. I admit that was a mistake. I regret including these smaller changes which should have been separate commits:

• #216
• #217
• #218
