Brian McGee 55ca4468cc fix: stalling on large file sets (#18)
When running against nixpkgs we were stalling. This was due to a long running read tx which was preventing any writes.

This breaks up reading the cache when walking the filesystem into many smaller read txs.

On my laptop I'm now getting the following with the echo sample:

```console
# fresh cache

❯ nix run .# -- -c --config-file ./test/echo.toml --tree-root ../../../github.com/nixos/nixpkgs
38825 files changed in 320.655826ms

# hot cache

❯ nix run .# -- --config-file ./test/echo.toml --tree-root ../../../github.com/nixos/nixpkgs
0 files changed in 252.920853ms%
```
