change mib in proc_info() now that i know about the proper mib call resulted in too small buffer length allocation

+#  archinfo
+
+Returns a list of running processes and the architecture they are running under.
+
+Apple M1/Apple Silicon/arm64 macOS can run x86_64 programs via Rosetta and most M1 systems currently (~March 2021) very likely run a mix of x86_64 and arm64 processes.
+
+Activity Monitor can show the architecture, but command line tools such as `ps` and `top` do not due to Apple hiding the details of the proper `sysctl()` incantations necessary to get this info.
+
+Patrick Wardle reverse-engineered Activity Monitor — <https://www.patreon.com/posts/45121749> — and I slapped that hack into a bare-bones command line utility `archinfo`.
+
+It returns columnar output or JSON (via `--json`) — that will work nicely with `jq` — of running processes and their respective architectures.
+
+Build from source or grab from the releases.
