Sanket slc history

[jeromesimeon]

Description

This is a draft PR to replace #709 which addresses some of the main issues with the original PR:

There are three major blocking issues with this PR:

1. Not properly based on the poc-slc branch

This PR is a proper extension of the poc-slc branch. The code was not rebased but instead is in a single new commit here:

2. deletes the whole cicero-transform package, instead importing a fixed version (why?!)

This PR properly depends on the cicero-transform package which is still present instead of deleted

3. tests are not passing (not sure why they aren't triggered on this PR). Below is a log

Two different issues with testing were fixed (with minimal knowledge of the intent):

1. some tests fails when the contract archive does not have history. this has been fixed by making history optional in the following commit:
2. Cicero-server tests fail due to a missing directory. This has been fixed by adding that directory back in the following commit:

As discussed during the last Tech WG call, I'm looking into recreating this PR properly.

Changes

• Changes from feat(*): state management of contract instances #709 for storing contract state in .slc archives
• Fixes issues with archives with no history
• Fixes testing issues with cicero-server changes needing a missing directory
• Fixes dependency issues with @accordproject/cicero-transform

Flags

• Could not do a proper rebase due to a dirty git history and the large number of changes, this version loses authorship and individual commits from @sanketshevkar
• Because of the testing issues and "hard reset" of the code, I have a somewhat lower confidence that this is a proper reflection of the original code and intent from its author. I will leave this leave this as a draft PR until I can get a review from @sanketshevkar and @martinhalford and confirmation that this is right
