feat: binary diff support; change scope to support multiple diff types/outputs

[steviegt6]

Since this started as a fork of Chicken-Bones/DiffPatch, it features specifically only an implementation of fuzzy diffing/patching (with support for exact and offset patches too). It may be useful to generalize the library to support binary diffs (as well as other textual diffs, perhaps?).
