Tested and used all build options on OpenBSD 7.4 with no issues.
Added a note about referring to depends/README.md for detailed instructions on required dependencies.
This was added in reference to a conversation in #29443
Move DataDirectoryGroupReadable 1 up a few lines to more clearly
communicate that it is required for the filesystem group to read the
DataDirectory.
Per the Tor documentation
https://2019.www.torproject.org/docs/tor-manual.html.en#DataDirectoryGroupReadable
"If this option is set to 0, don’t allow the filesystem group to read
the DataDirectory. If the option is set to 1, make the DataDirectory
readable by the default GID. (Default: 0)"
