add nyx.json

[heather7283]

First, create a $XDG_CONFIG_HOME/nyxrc file with the following content:

data_directory ~/.cache/nyx

Note that you can't use variable substitution inside nyxrc, so you will have to hardcode your XDG_CACHE_HOME.
Alternatively, disable caching to disk:

data_directory disabled

Finally, in your shell startup file:

alias nyx="nyx --config $XDG_CONFIG_HOME/nyxrc"
