Refactor uploading system deduplication using hash

[rugeli]

Problem

What is the problem this work solves, including
closes #316

Solution

What I/we did to solve this problem

• used hashlib to generate a unique hashes for each doc (any changes will produce a new hash)

• removed the should_write method from each doc class

• updated unit tests
  with @ascibisz

• introduced new field dedup_hash

Type of change

Please delete options that are not relevant.

• Refactor (non-breaking change which adds functionality)

Steps to Verify:

1. Upload a recipe to your firebase dev db
2. Re-upload the same recipe to confirm the hash prevents duplicates
3. edit recipe's name and a nested data field, then upload again to test if new doc and new recipe are detected
4. run pytest

TODO: troubleshoot upload_composition to detect any changes in inner compositions and create new top level compositions.

i.e. updating the count of A should create a new comp A and a new comp space. These new compositions should be linked to the corresponding recipe as references.
