It doesn't work on Android, and I can't fault it for that (Platform difference)
but it also drags in `uom` which has a bunch of template magic that takes
forever to compile, and I'm pretty sure it's dragging down my compile times.
I tried to build `ptth_server` on nightly to get compile timings, and heim
depends on `socket2` which failed to compile.
And I never ended up using the CPU monitoring. So heim is gone now.
The password checking is not necessary with the new process of generating
high-entropy Base64 passwords and then approving them on the relay.
The password file takes a lot of space and this doesn't need to be part
of ptth_server's public API, if there is one, anyway.
I forgot to set the version in Cargo.toml files for 1.0.0.
I'm not gonna do 0.x versions because this is already live somewhere
and I don't like that 0.x adds complexity to versioning.
