Tesseract visualizations

[noajshu]

Created a visualizer for Tesseract execution.
Will add some visuals shortly

Example usage:

bazel build src:all
./bazel-bin/src/tesseract --pqlimit 1000000 --beam 10 --sample-num-shots 100 --det-order-seed 13267562 --circuit testdata/colorcodes/r\=9\,d\=9\,p\=0.001\,noise\=si1000\,c\=superdense_color_code_X\,q\=121\,gates\=cz.stim --sample-seed 717347  --verbose --threads 1  > logfile.txt
python viz/to_json.py logfile.txt -o logfile.json

then upload logfile.json to the 3dviewer.html tool page

Here is a heavily-compressed GIF to show what this looks like decoding d9 color code shots:
