Library not loaded: liblept.5.dylib

**Describe the bug**
When installing and trying to use this on an M1 Mac, there is an issue with dependencies not being found. Specifically:
`dyld[86379]: Library not loaded: /opt/homebrew/opt/leptonica/lib/liblept.5.dylib`

**Setup**
- Apple M1 Pro. Sonoma 14.1 (23B74)
- Installed with go and with brew

**To Reproduce**
Steps to reproduce the behavior:
1. Install vhs
2. Run a tape

**Solution**
I made a copy of the following 3 files
- /opt/homebrew/opt/leptonica/lib/libleptonica.6.dylib
- /opt/homebrew/opt/leptonica/lib/libleptonica.a
- /opt/homebrew/opt/leptonica/lib/libleptonica.dylib

and then renamed the copies to these respectively:
- /opt/homebrew/opt/leptonica/lib/liblept.5.dylib
- /opt/homebrew/opt/leptonica/lib/liblept.a
- /opt/homebrew/opt/leptonica/lib/liblept.dylib

Start by reproducing the M1 macOS setup described in the issue: install vhs with Go or Homebrew and run a tape. Trace how the application locates its leptonica dylib dependency; done means a tape runs without manually copying or renaming library files.
