This change contains 2 improvements to the tvix-store copy command:
1. Allows reading the reference graph from stdin, using `-` argument
2. Supports json representation produced by `nix path-info --json`
command.
In general it makes is easier and faster to import arbitrary closures
from an existing nix store with e.g the following command:
```
nix path-info ./result --json --closure-size --recursive | \
jq -s '{closure: add}' | \
tvix-store copy -
```
