Release/v0.2.4

1. Added azure dir to .dockerignore
2. Updated Dockerfile to use newer version of node (16 is end of life)
3. Modified config.yaml to point to the correct S3 paths for comstock & resstock.
4. Modified the code to allow for custom table prefixes. The autogenerated ones were very long and unwieldy.
5. Updated config.yaml to use the Table Prefix input for all datasets.

Note that generate_table_prefix from utils.py is no longer used. Should I remove?
