Load .jpk-qi-data metadata using jpk-reader-rs package

[bicarlsen]

Speeds up loading .jpk-qi-data files by using the jpk-reader-rs package to load metadata.

Addresses #41, reducing load times of standard files by ~10x. For the test file it reduced the load time from more than 120 minutes to about 15.

I kept as much of the original JPKReader as possible for this first pass. There is still quite some performance to be gained though, as the same test file loads in 20 seconds from the Rust crate.

While probably not yet ready to be merged, I'm hoping can use it so we can address any issues that arise and continue to imporve upon performance.

This also incorporates #44.

This new version optimizes get_metadata. Load times are down to about 130 seconds (60x faster than original) on my test data.

Once this is more thouroughly tested, it should be good to go.

There may also be some optimizations that can be applied elsewhere:

1. File list is sorted, so you can use bisect to find items in it.
2. Shared properties is repeatedly sorted and walked. Instead this can be done once at initialization.
3. hierarchy was rewalking the file list. It now just happens at initialization.
