feat: add filecoin to dynamic cli

[mikeseese]

This PR is a continuation of the work that was done in #726, but it includes more. Here's the full list of this PR's intention:

• Add the Filecoin package to the CLI interface properly
  • This includes keeping the @ganache/filecoin package as a peerDependency for @ganache/flavors and failing if the package cannot be found
  • Due to the above, a link.filecoin script was added to the root package which is meant as a development helper to link the filecoin package for usage
  • This peer dependency architecture also required me to provide separate type declarations to prevent a circular dependency. I have a strong feeling @davidmurdoch will not be a fan of this, but I believe this is the only setup that will work in production. I could be wrong and am open to alternatives. I provided a root script tsc.filecoin.declarations to allow for quick ease and file cleaning via pretty-quick
  • Neither of these two things (root linking script and type declaration generation) are currently automated (meaning the developer has to call them when they need it). I'm not sure if/who you want this in your development process, so I left it out as it's a trivial thing to setup later. I can do this if you let me know what the desired dev experience should be.
• Preliminary reorganization of tests in @ganache/filecoin. I originally intended to fix tests, but I found myself spending too much time fixing tests that were no longer fully applicable due to large overhauls in @ganache/filecoin/src/things. I didn't want to spend much time getting the tests to pass in this state. You can see tests are passing in the subsequent branch. I strongly encourage we do not fixate on tests that are failing prior to this branch when this branch does not alter the behavior behind those tests.
• Some other minor housekeeping stuff (some code styling, etc)

All of the filecoin branches are currently based off of #757 as it helps my development process. This adheres to that if it is accepted. It will be changed if #757 is rejected.

I'm closing this PR because @tcoulter wants PRs that have passing tests. Instead we are creating a PR with the next branch (feat/filecoin-chainnotify) that targets filecoin (so it'll also include this work)
